how did the testing of protection relays done through
why they were using TRIAC instead relay in some controllers
and what is the advantages.
What is given by the definition in BIL IMP/PF = 950/395 kV.
This was found in a name plate of a power transformer.
how is the incoming cable size calculated for a given current
rating of a panel??
How does "OUT OF STEP" relay ,for Synchronous motor
pls tell us AC plant are how do work and parts name with
What fomula is used to calculate:
1. rated frequency withstand voltage, and
2. rated lightning impulse withstand voltage.
WE ARE PLACE A NEW 75 KW MOTOR FOR JPF.IT IS CONNECTED IN
M.C.C. WHEN WE ARE STARTING M.C.C.INCOMER IS TRIPPED.THEN
WE ARE CONNECTED IN P.C.C WITH A MM30 RELAY PROTECTION THEN
WE ARE STARTED MOTOR WILL RUN SMOOTHLY.
