Answer Posted / logachandran m

We are using Both Line& Bus PT(Potential Transformer) But different application.
1. Line PT- This PT using on main Incomers to Bus bar system or Main out going from Bus system,it will protect the particular feeder system. Ex,Transformer incomers,Generator incomer,etc,....
2. Bus PT- This PT using on Particular Bus bar system, It will protect the Bus Bar. Its will useful for Bus bar to bus bar synchronization or Bus bar to any source(Using with line PT)

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 ?

We have a couple of oil tanks at our plant. One of them does not have a lightning arrester installed. My question is it necessary to install an arrestor on every tank or will this particular one be covered by the arrestor installed on the ajdacent tank, Since all the tanks are close to each other. Basically, I want to know that if these arrestors or protection works in a parituclar area of effect or influence. Thanks
