Anyone who has ever played roulette, either in a brick-and-mortar casino or online, has thought of various ways to beat the game. Over the long history of roulette, many strategies have been created but so far none of them has been proven to guarantee players consistent wins, especially in the long run. Traditionalists would argue that classic betting systems such as the Martingale, the Fibonacci, or the Labouchere are the best way to win in roulette, but an increasing number of roulette players are now relying on more modern methods. And some of the most popular tactics today are so-called Double Street/Five Quad systems.

This is a relatively modern idea according to which you need to cover large portions of the roulette table so that you can have greater chances of winning. Of course, similar concepts have existed in the past, but they have never been particularly popular among gamblers as they were seen as unreliable. In reality, there is no roulette system that can provide certain, solid, and consistent profits.

Some tactics where you cover most of the table may offer players to “win” on every single spin. That is, indeed, possible. But a win is not always synonymous with profit – logically, when you bet on larger sections of the table, you also wager more money. If your bet is not balanced well, you may win the spin and at the same time, lose funds. This is why the Double Street/Five Quad systems are so effective – the allow you to cover a large area of the roulette table without risking too much.

What Exactly Are The Double Street/Five Quad Roulette Strategies?

These roulette systems are two similar variations of each other, both are based around covering a large amount of the board with a relatively small bet. With the double street quad system, a grand total of 17 numbers are covered on each spin, almost half of all. With the five street quad, further 4 numbers are covered. So it’s fair to say that, with both of these variations, one of your numbers will come up pretty regularly.

Double Street Bets

For those of you who don’t know, the street bets are three consecutive numbers across the table (e.g. 1,2,3 is a street, 4,5,6 etc…; or any three numbers that are in a line). A double street bet covers two streets, you can see in the images below how this is placed – the chip must be on the border of the numbered grid of the layout, right between the two streets. Also known as a 6 line bet, the double street covers 6 numbers and has a probability of 16.2%. At the same time, it offers a payout of 5 to 1.

Quad Bets

Often called corner or square bets, quads are bets on blocks of four numbers. In European roulette, the probability of this combination is 10.80% and if it hits, players are paid 8 to 1. As the name suggests, this type of bet covers four numbers of your choosing, and you place a quad bet by placing the chip in the centre of these four numbers. Hopefully, I don’t need to explain what a single number bet is. (For more information on types of bets, see my ‘Roulette Rules’ page).

So Which Numbers Do I Bet On?

As explained above, there are different strategies to cover a large portion of the roulette table – you can bet on 35 numbers, you can bet on 17 splits, on 11 streets, on 5 double streets and many other. The key to finding the best cover-the-table system, however, is finding the balance between the size of your bet and the coverage you can secure. Otherwise, you will most probably win all bets but you will not be able to make profits, as you will lose more than you win. For this reason, many roulette players in recent years prefer the double street-quad strategy and the five quad strategy when trying to increase their chances of winning and leaving the table with a profit.

The Double Street Quad Roulette Strategy

Here, you will be betting two chips each on two double streets, along with one chip on a quad and finally one chip on a single number, as in this example. Overall, you will place bets on 17 numbers, which is almost half of all numbers on the wheel. As you can see, the numbers covered are 4 to 9, 16 to 21, 26, 27, 29, 30, and 34 as a straight bet.

You need to place a total of 6 chips – your street bets will reward you at 5:1, the quad bet 8:1 and obviously the single number bet will pay out 35:1, which makes it the real money maker. The idea is quite simple – the double street and quad bets keep you going. The single number bet is the one you’re really waiting for and should leave you with a healthy profit by the time it comes up.

The Five Quad Roulette Strategy

Rather than using street bets, this five quad roulette system means you’ll be placing five quad bets and one bet on a single number, as in this example. The quads are forming a zigzag shape on the table layout and include 1-2-4-5; 8-9-11-12; 13-14-16-17; 20-21-23-24; and 25-26-28-29. The straight bet is on 33.

This system works in a similar way to the double street method, only this time you’re covering more of the board, in fact, more often than not your numbers will come up. The reason behind this is simple mathematics – you bet on 21 numbers, 12 of them are black, while 9 are red. Just like the double street quad bet, this system requires placing only 6 chips on the table.

So Are These Systems For Me?

Both of these strategies are well suited to players with a relatively low bankroll, or someone who doesn’t want to risk too much. With so many numbers covered, and relatively small bets being made (of course, the value of the chip depends entirely on you), the odds on consistently coming up with a loss on each spin is negligible. Indeed, compared to other strategies, these two methods come with low risk, especially the five quad system where your bet covers more than 50% of the table. It is a wonderful solution for less confident players who have, until now, placed their chips only on the outside bets where both the risk and the payout are even lower.

Taking all this into consideration, we may conclude that these two tactics are better. Yes, losses may be rarer than when you use some other strategy. However, this does mean that the rewards aren’t quite as high as other systems. Even with the single number bet, don’t expect to go in with £100 and come out with £5000, it just isn’t going to happen. The idea is that along with the good coverage of the table, you will have a good, lucky day and you will be able to leave with a decent profit.

These two strategies are designed to provide punters with more control and with small, but frequent wins. For many roulette players, a system with a good longevity is preferable to a system offering huge rewards once in a while.

Conclusion

These systems are both appealing and I personally lean more towards the double street quad but that’s more of a personal preference. They may not be perfect, but they may prove to be extremely effective. If you have the patience (and you should if you want to be a successful player), these roulette methods can provide a nice profit over a relatively long period of time, without a great risk.

This is why their popularity is steadily increasing in recent years – these strategies are slow, but solid and reliable and unlike many roulette systems, they do not depend so heavily on luck and chance. And as you probably know well, luck is never enough when it comes to casino games where the house has the advantage. While the Double Street/Five Quad Roulette Systems will not be able to overcome the fixed odds of the game, they will greatly increase your chances of making a profit when playing roulette.

Zig Zag transformers are a special-purpose three phase transformer with a ZigZag or 'interconnected star' winding connection. Zigzag transformers are used to create the missing ground in an ungrounded 3-phase system by providing a path for the neutral to ground.

Throughout the USA, many utility companies are requiring renewable power providers (Wind, Solar, Hydro) to install grounding transformers at their tie point to grounded, ungrounded or undergrounded systems to provide a ground reference.

The best way to resistance ground a power system is to obtain the system neutral through a generator or transformer with a wye-connected winding.

However, a system neutral may not be available, particularly in many older low voltage systems and a significant number of existing medium voltage systems. To avoid the high cost of replacing a source transformer, an existing delta-connected system can be grounded using a zigzag transformer to form an artificial neutral, then connecting a resistor between the newly created wye-point and ground.

In delta connected transformer, a zero sequence (i.e. an unbalanced current during the fault) is unavailable and therefore components are not protected which result in additional stress and increased heat on the system. Zig zag transformer are a specialty transformer built with high end insulation materials, copper conductors and superior core steel to create a robust unit that provides a neutral during the ground fault.

Zig zag transformer are designed to offer a low impedance, creating a path for zero sequence components under fault conditions and prevents system voltage rise in the unfaulted phases which makes a zigzag transformer a very good earthing transformer. In the event that the current has to be limited during the fault condition, a suitable neutral grounding resistor can be added to the system.

Acutran Neutral Grounding Systems (single or three phase) can we combined with neutral ground fault relays and current transformers to automatic create an open circuit during the fault condition is the system can not automatically correct itself.^[1]

A zigzag transformer is a special-purpose transformer with a zigzag or 'interconnected star' winding connection, such that each output is the vector sum of two (2) phases offset by 120°.^[2] It is used as a grounding transformer, creating a missing neutral connection from an ungrounded 3-phase system to permit the grounding of that neutral to an earth reference point; to perform harmonic mitigation, as they can suppress triplet (3rd, 9th, 15th, 21st, etc.) harmonic currents;^[3] to supply 3-phase power as an autotransformer (serving as the primary and secondary with no isolated circuits);^[4] and to supply non-standard, phase-shifted, 3-phase power.^[2]

Nine-winding, three-phase transformers typically have 3 primaries and 6 identical secondary windings, which can be used in zigzag winding connection as pictured.^[2] As with the conventional delta or wye winding configuration three-phase transformer, a standard, stand-alone transformer containing only six windings on three cores can also be used in zigzag winding connection, such transformer sometimes being referred to as a zigzag bank.^[2] In all cases, six or nine winding, the first coil on each zigzag winding core is connected contrariwise to the second coil on the next core. The second coils are then all tied together to form the neutral, and the phases are connected to the primary coils. Each phase, therefore, couples with each other phase, and the voltages cancel out. As such, there would be negligible current through the neutral point, which can be tied to ground.^[5]

Each of the three 'limbs' are split into two sections. The two halves of each limb have an equal number of turns and are wound in opposite directions. With the neutral grounded, during a phase-to-ground short fault, a third of the current returns to the fault current, and the remainder must go through two of the three phases when used to derive a grounding point from a delta source.^[6]

If one or more phases fault to earth, the voltage applied to each phase of the transformer is no longer in balance; fluxes in the windings no longer oppose. (Using symmetrical components, this is I_a0 = I_b0 = I_c0.) Zero-sequence (earth fault) current exists between the transformer’s neutral to the faulting phase. The purpose of a zigzag transformer in this application is to provide a return path for earth faults on delta-connected systems. With negligible current in the neutral under normal conditions, providing the defective load will be automatically disconnected in a fault condition, an undersized transformer may be used only as short-time rating is required (i.e. the transformer can only carry full rated current for, say, 60 s). Impedance should not be too low for desired maximum fault current. Impedance can be added after the secondaries are summed to limit maximum fault currents (the 3I_o path).^[7]

A combination of Y (wye or star), delta, and zigzag windings may be used to achieve a vector phase shift. For example, an electrical network may have a transmission network of 110 kV/33 kV star/star transformers, with 33 kV/11 kV delta/star for the high voltage distribution network. If a transformation is required directly between the 110 kV/11 kV network an option is to use a 110 kV/11 kV star/delta transformer. The problem is that the 11 kV delta no longer has an earth reference point. Installing a zigzag transformer near the secondary side of the 110 kV/11 kV transformer provides the required earth reference point.^[8]
