I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

IFD Corporation’s Internal Fault Detector is an inexpensive sensor used in distribution transformers that indicates the presence of an internal fault inside the transformer. Dec. 7, 2010 IFD ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

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 ...

A bipartisan group of 12 U.S. senators on Jan. 18 introduced a bill that could freeze the Department of Energy’s (DOE’s) implementation of updated energy efficiency standards for distribution ...
