How to test Alternator stability test for REF relay
Dear Sir/Madam, I have one questions we have three steam turbines and one Gas turbine and our industry linked with the public network, we have protection system one of the protection is reverse power we can export just four MW only i would like to ask about how to calculate the reverse power. Thank you in advance best regards
In our plant we have installed new MCC with ELR and CBCT which is detecting some leakage current in the system but it leading to some confusion when to check that in which feeder which is drawing current we put off the whole panel itself but still CBCT detecting some leakage current so can anybody ans me , where i am going wrong or how to detect whether its actual leakage or CBCT malfunctioning.
