Electromagnetic compatibility (EMC) failures in control wiring cause false trips that halt production, frustrate operators, and erode confidence in protection…
A 50 ms voltage dip during a grid disturbance can drop an electrically held contactor—disconnecting a 2,000 kVAR capacitor bank…
Every switching device in a medium-voltage network depends on metal-to-metal contact interfaces to carry load current. These interfaces—measured in tens…
Medium-voltage circuit breakers need auxiliary devices to initiate opening under abnormal conditions. Two mechanisms dominate: the shunt trip coil and the undervoltage release…
A 6.6 kV crusher motor feeder tripped on overcurrent. The protection system worked—partially. One HRC fuse cleared a phase-to-ground fault…
A contactor coil running hot is a coil running toward failure. In panel enclosures where ambient temperatures climb past 45°C—common…
In medium-voltage distribution systems (3.6 kV to 12 kV), switching devices are often misunderstood. While vacuum circuit breakers (VCBs) get…
A contactor failure at 2 AM means one thing: production stops until you fix it. This field cheat sheet eliminates…
Medium-voltage contactors switch power at 3.6 kV to 15 kV, but their control circuits operate at much lower auxiliary voltages—typically…
