A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

This is due to the inductive nature of a transformer load. Using anything less than a NEMA Size 4 for our transformer above would be a violation of Sec. 110.3(A) and (B) of the 2014 Edition of the NEC ...

The new LTC135 uses dynamic resistance measurement (DRM) techniques to perform advanced diagnostic tests on transformer load tap changers. Designed for use in conjunction with the company’s circuit ...

Preventive maintenance keeps production running for transformers. A Load Tap Changer (LTC) failure can be catastrophic to the rest of the electric power system. SDMyers, a transfomer reliability ...
