Why is it that bus reactors are not accompanied by a neutral grounding reactor whereas a line shunt..

Answer / subbarayalu

In EHV Line, if there is single pole auto reclose used, during single phase fault, the faulty line may have arc current due to resonance which will disturb the auto reclose. Also, there will be transient recovery voltage. To compensate this effect we require Neutral Reactor in the EHV line. Whereas the same Auto Reclose condition will not be in Bus Reactor breaker. Hence, neutral grounding reactor is not required in Bus Reactor

We use ungrounded DC system (220V/110V) for control and protection system in substations etc. Suppose we have long 2 core DC cables running from our DCDB in control room to the load (length of around 2 to 3 km). Do we need to protect these long DC cables from earth leakages or not? If yes how?
