Hi everyone!
There is already done MV cable termination in MV switchgear. It is screened termination NKT,on XLPE cables and there is 3 donut current transformers for each of them.I know that screen Cu wires of each cable must pass back through Current transformer, but what about wire which...
Hi all!
It is not clear and I can't find instruction about core balance current transformer and screen connection of MV termination.Ground wires of cable are routed back throught Core balace current tranformer....do we need to do the same for cables which earth semiconductive layer of cable...
Hi,all!There is power factor controller on LV network.A group of outputs...which control contactor for stages of capacitor banks...is not working...the reason is not interesting...loose connection somwhere inside the controller...Is there any technical reasons...not to connect 2...
Hi everyone!Can sameone explain is it possible to fill up sealed transformer on site?There is a drain valve on the bottom of transformer.After few procedures of oil sampling...how to prove oil level is ok?There is no oil level indicator.Can someone give me a procedure?Also there is a bad gasket...
Most of companies which work on this field,talks about inductive energy compensation.Most of solutions are based on condensator switching controllers.I understand that this is most common,but what about compensation of capacitive load?How is switched reactor?What kind of controllers are used?Did...
Hi everybody!
I am thinking about MV customer distribution substations....like a rule in my region MV switchgear is configured from left to right:input feeder/output feeder and after that transformer feeder.Last years manifacturers produce stations in witch first is transformer feeder..from left...
