For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...
Menlo Park, Calif. — Raychem Circuit Protection, a business unit of Tyco Electronics, has introduced the PolySwitch LVR series of resettable circuit protection devices to help protect electric motors ...
The PolySwitch LVR Series of resettable circuit-protection devices protect electric motors and transformers from overcurrent and overtemperature damage. The series includes parts rated for line ...
A. Except as permitted by Sec. 240.21(A) through (H), overcurrent devices must be placed at the point where the branch-circuit or feeder conductors receive their power. Taps and transformer secondary ...
Note: All Code references are based on the 2014 NEC. The NEC has separate sections for transformer feeder protection and transformer protection. Article 240 lists requirements for transformer feeder ...
An ideal protection device must limit the energy going to the load being defended, to a sufficient minimum level, such that the load is not damaged. The protection device must survive this energy ...
Omicron's CT Analyzer provides fast and cost-effective testing and verification of current transformers for protection and metering applications. It automatically determines all relevant current ...
