What happens if the Capacitive Voltage Transformer Primary neutral is not earthed. There is a CVT between Transformer and source, and the CVT neutral of the transformer is not earthed, does it effect the transformer while charging or does it effect the transformer charging process.
The shot circuit in any winding of transformer result? Explain
Why LED light has advantage of rapid reflection ,although other lights alse reflect.? and this light is considered to be best for transmission usage in case of Free optics
Differentiate between kirchhoff’s first law and kirchhoff’s second law?
state the working principle of incondenscent tube?
why do you add the load short circuit impedance when considering short circuit amperage. It seems that you should only consider supply. If you need to consider loads and you don't know what loads are to be added , what would be a good sub-transient reactance rating for the loads?
Could you measure voltage in series?
How does cost of generation from hydropower plant compare with other sources of electricity?
Whether amorphous core transformer is available in India?.If available then up to what rating of voltage and KVA?.
why we are not giving the zone 1 trip command to the master trip relay
I am getting above 60 V as open delta voltage against single phase unit ICT at tertiary delta formed and ICT getting trippped on NDR. ICT tested and found in order. PTs provided on tertiary are tested and in order. what may be the reason?
I am using submission of two ct in one and half scheme for 67/67N protection. Both CTs star point is grounded separately near ct box.Will two point ground give wrong tripping to 67/67N during fault or no matter.
