When designing ground-fault protection (GFP) for a power distribution system, you should always consider the nature of the power source. If the power source is from a separately derived system, you ...
One of the most important aspects of a safe electrical power system is the proper performance of ground-fault protective equipment. Mandated by the National Electrical Code (NEC), Art. 230.95(C) ...
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 ...
Created to protect personnel from electric shock, GFCI-type operations now help protect equipment as well. • Ground-fault sensing now protects equipment as well as personnel. • The magnitude of ...
VALENCIA, Calif.--(BUSINESS WIRE)--As aging transformers face increasing electrical and environmental stress across global power networks, traditional monitoring methods, such as periodic sampling, ...
An internal fault can be violent enough to blow the lid off a transformer. Catastrophic failure of an overhead transformer is a rare occurrence, but it does happen. Electrical systems are designed so ...
