5 7936For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
1513length of 4 core cable 95mm from substation LV VFD panel to Motor at field approximately 150 meter. Motor stop and power has been isolated from LV MCC ( Substation )to disconnect Motor for services. After Motor completed service propose to reinstall and reconnect Motor Cable, found earth cable sparkling during touching at metal / motor body. Inspect by clamp meter found earth cable have current flow AC 1-2amps and all earth cable at MCC LV also have current flow as same value. why it is happen?
