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.
