if two transformers are parallel & both have fault short
ckt. impedance of 50KA in each case will it increase or
decrease show example?
if installing the transformer why put the sprit the stone ?
what is formula in determining the size of Circuit Breaker for transformer with the following specifications. 7 units of 1600 volts (primary) and 400 volts (secondary). Both Primary and Secondary will have a circuit breaker which is SF6. What should be the Switchgear Main Breaker Size anf the sizes of each brances Circuit Breaker for Primary.
Since phi is the angular displacement between V & I, then why we use phi in power triangle ie. when showing active, reactive & apperent power in triangular manner & if it is ok then where is V & I in the triangle.
Define active and passive network?
what do you mean by puncturing of insulator by ice -coating?
What is reactance? what is the function in Auto transformer and why high leakage reactance?
what is the purpose of slope in the differential relay?why we are using two slope?but in busbar differential we are using only one slope.why?
List examples of current sources?
WHY SPEAKER OUTPUT IN WATTS??
Why Water motor is not taking a load or pressure while everything is correct. (Note: Motor running properly)
what are the sections in a high voltage system(eg:incomer,buscoupler,isolator
what is the difference between VARIAC,AUTO TRANSFORMER,DIMMERSTAT.
