Current Limiting Protector (CLiP) | GW Electric

Features: System Upgrade — without replacing under-rated equipment such as circuit breakers, reclosers, switches or bus. Reactor Bypass — to eliminate costly operating losses and eliminate voltage regulation problems.

electrical connectors altitude de-rating?

Ok, please dont laugh. well, laugh, just not at ME. Somehow a couple of our engineers think that mil-spec electrical connectors are subject to a 70% de-rate at 20,000 feet.

Multimeter measurements on adjustable speed drives utilizing the new Fluke 87V DMM Application Note. In the past, motor repair meant dealing with traditional three-phase motor failures that were largely the result of water, dust, grease, failed bearings, misaligned motor shafts, or just plain old age.
