In the start you mentioned that 250/200/75 is 250 on primary and 200 is on secondary why? Bec power remain same on both side right?

What criteria can i look to find if the breaker pass the test?
@electricalexpres 2 ай бұрын
Criteria depends on what limits manufacturer of Breaker has given for Opening and Closing time of Circuit Breaker, if it is under limit, Breaker passes the test.

Brother... I need to test hi pot for transformer 22kv /430 v Dyn11 3.36mva How to apply primary R Y B short and inject test volate Secondary RYBN short and Ground Hi pot return wire connwction also connected to ground Is that correct way to do hi pot.. My doubt is if we doing stability in transformer we applying 415 V in primary and we donshort insecondary its creat huge current... As same we in hi pot when i am going to inject hevy voltage is not a dangerous? Pls clarify
@electricalexpres 2 ай бұрын
Hipot test we do for checking the healthiness of the insulation of transformer, we apply DC voltage and take refrence to the ground. If secondary side is shorted and grounded, current will not flow through secondary since it is grounded.
