OLR - OVERLOAD RELAY
MPCB- MOTOR PROTECTION CIRCUIT BREAKER
IF SHORT CIRCUIT IS OCCURED IN CIRCUITS ,
OLR - MELT THE COIL TO TRIP AFTER ITS AUTOMATICALLY
CAME NORMAL POSITION BUT,
MPCB- TRIP THE COIL IT WILL BE MANUALLY SWITCH ON THE RUN
THIS IS THE DIFFERENCE

WHTA IS LIMT OF LEAKGE CURRENT OF 11 KV 1 CORE 1000SQ.MM. XLPE CABLE.LOAD ON CABLE IS AROUND 600AMP .LENGTH 500 MTRS.
With a phasor diagram show the effect of increasing the field current of a generator supplying a constant real power and connected to a grid system.
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.

ASTM D 3455 - Standard Test Methods for Compatibility of Construction Material with Electrical Insulating Oil of Petroleum Origin has been used for Testing Transformer Oils with a product placed in it. Aged Control Oil has a Power Factor of 0.032% at 100°C. Aged Oil with a Test component has a Power Factor of 0.093% at 100°. Is this increase acceptable? If not why? How much increase is acceptable?
