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?

This is 3 Winding auto-transformer Nameplate, 200MVA is Transformer rating in Intermediate voltage Winding

If 1S1 and 1S3 are connrctected no need to short other two terminals However in case no external connections are made then shorting of all 4 terminals is essential

What criteria can i look to find if the breaker pass the test?
@electricalexpres2 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
@electricalexpres2 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.
