Answer / koodalingam

To protect the primary winding of the potential
transformer.If you not earthed the system,the unbalance
voltage will appear between neutral and earth.This voltage
can damage winding.

Why are some relay circuts designed to have the ct current flow through the neutral instead of the phase wire, such as in some diff relays?

1 Answers  


We have a 33/11kv switchyard having 12.5 MVA power transformer. We export & import power through this transformer. When we export power, the PF will be depend on GRID PF & when we import power the PF will be depend on our load PF. but the problem is that,when neither we export nor import but our 33KV vCB is in close position,our meter read the power factor 0.14 to 0.25 at that moment. So how can be we improve the power factor at that moment.
