"A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines; it can be described as both jagged and fairly regular. Traditionally a "zig" points in the left direction (/) and a "zag" points right (\). From the point of view of symmetry, a regular zigzag can be generated from a simple motif like a line segment by repeated application of a glide reflection." ~ Wikipedia

A zigzag transformer is used in connection with 3 phase and is made up of 6 coils connected in a "Y" manner. Each leg of the "Y" is made up of a coil on a different phase leg of the transformer. The neutral formed by the zigzag connection is very stable. Therefore, this type of transformer, or in some cases an auto transformer, lends itself very well for establishing a neutral for an ungrounded 3 phase system. Many times this type of transformer or auto transformer, lends itself very well for establishing a neutral for an ungrounded 3 phase system. Many times this type of transformer or auto transformer will carry a fairly large rating, yet physically be relatively small. This particularly applies in connection with grounding applications. The reason for this small size in relation to the nameplate KVA rating is due to the fact that many types of grounding auto Transformers are rated for 2 seconds. This is based on the time to operate an overcurrent protection device such as a breaker. Zigzag transformers used to be employed to enable size reductions in drive motor systems due to the stable wave form they present. Other means are now more common, such as 6 phase star.

What did front line trenches have a zigzag pattern?

Front line trenches had a zigzag pattern to minimize the impact of enemy fire and shrapnel. This design reduced the risk of a single artillery shell or bullet hitting multiple soldiers at once, as the angles created barriers that obstructed line of sight. Additionally, the zigzag shape helped to contain any explosions or blasts within a section of the trench, enhancing the overall safety of the troops.


What is the name of the ski race zigzag down the hill?

There are a few...Super Giant Slalom, Giant Slalom, and Slalom. Depends on how wide the turns are.


Speed of World War 2 convoys crossing the north Atlantic?

The speed of the convoys going across the Atlantic depended on the slowest ship in the group. The convoys were further slowed down by traveling in a zigzag pattern to avoid being an easy target for U-boats. The speed of a convoy was seldom more than 15 knots.


Why are trenches zigzag and not straight?

Because if an enemy got into the trenches, theycould stand at one end with a gun and fire continuously and wipe out everyone, having zig zags helps prevent this! The trenches were also zig-zagged because if an enemy shell landed in the trench, it could wipe out a whole platoon if the trench was straight!


How did they dig the trenches in world war 1?

During World War I, trenches were primarily dug by soldiers using basic hand tools such as shovels, picks, and spades. The process was labor-intensive and often dangerous, as soldiers had to dig under the threat of enemy fire and shelling. Techniques varied from the use of small teams to large groups working together, and they often employed methods like zigzag patterns to minimize the risk of being hit by enemy fire. Additionally, some areas were reinforced with wood or sandbags to prevent collapse and enhance protection.
