Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

TRAX from Megger is not just another multi-functional test instrument, but rather many intelligent instruments built into one box. TRAX from Megger is not just another multi-functional test instrument ...

Part 1 of this three-part series laid out an overview of a proposal to create a numerical health index and establish a practical program for power transformer maintenance. Part 2 breaks down each of ...

Effective transformer maintenance depends on dissolved gas analysis. Effective maintenance of liquid-filled transformers begins with prevention of failure by testing transformer oil for unusual ...

Electrica signature analysis (ESA) uses the magnetic field in the air gap of an electrical machine to evaluate power quality conditions. Dry and oil transofrmer types are subject to problems ...

You can purchase test equipment that will allow you to examine the loop gain and loop phase properties of an operating feedback loop and, that purchased equipment will deliver useful results over a ...
