Greeting all,
open delta and broken delta are two same words or there is a difference.

Greeting all,

It is not the same setup.Two different words. Same set up, but the broken one is created by default. I assuming this is just a question about English?
It is not the same setup.
A broken delta is used to measure 3Vo (the sum of the delta voltages) for a ground relay.
Once you have the zig-zag, you can use it to measure ground currents. The broken delta just for protection schemes.The use of a zig-zag transformer is discussed as a means of low reactance grounding, not protection. A delta-wye transformer is shown as a form of low resistance grounding.
Once you have the zig-zag, you can use it to measure ground currents. The broken delta just for protection schemes.
Yes, the broken delta is for ungrounded systems.The broken delta is used on ungrounded systems.
Using the zig-zag would ground the system, so other types of protection schemes would be used.
It is tied to the SBMTT relay (SomebodyBetterManTheTelephones) and the CYB relay (if you don't know this one, you are in trouble already). :grin:Broken Delta voltage is used on distance protection scheme to protect against transmission line ground faults
