Great sirji

[@arindamguha4571]

R/sir
First of all thank you very much for your technical videoes. I want to know regarding the contactor coils. How to determine that the coils are weak or not. There are several types of contactor with coil resistance. How to calculate there minimum and maximum coil resistance and when it will change to prevent breakdown.
Thank you very much sir

Sir
Jb hm SF6 Circuit Breaker ki Condition Monitoring karte hai to usme Gas ka Pressure uske Pressure Gauge se pta chal jata hai ya usme gas leakage hone ki condition me bhi pressure gauge se pta chal jata hai pr VCB me agar Vacuum leak ho jaye to kaise pta chalega. Please sir
