Purpose of INSTRUMENT TRANSFORMER (CT & PT) is to reduce
the voltage and current respectievly.In EHV/HV/MV voltage
and current for the protection/metering canot be taken
directly as its voltage is very high and required huge
insulation and cost, so PT & CT is using to stepdown
voltage and current. Protection CT and measuring CT are
different class of manufaturing and secondary current
normally one amps but it can be manufactured as per
customer requirement. in 415 V also CT is using if current
is high.

What is the unit audit? if our Max demand is something and we found much more unit then how to improve our max demand?
I don't understand why when we connect high voltage source in DC to electronic motor , we must add capacitor and resistor in parallel ? (I know that we use capacitor because we want to absorb the current that in the first second electronic motor in opposed with current course produce. ) what are the feature of Resistor and in such situation ?
