International technical platforms such as the IEEE PES Transmission & Distribution Conference and Exposition play a key role in shaping these developments by bringing together grid operators, ...

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

With the new MCT1605 test set from Megger, comprehensive testing of current transformers – including multi-ratio types – can be carried out quickly and easily. With a single push of a button, the ...

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 ...

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 ...

So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

The units feature an intuitive orange three-position (Operating, Shorting and Measuring) disconnect lever. Engaging the lever fully automatically short-circuits the transformer when using the required ...

Liou Electronics’ product offerings encompass a variety of current transformer types, including the widely used Center Through Hole (Split Core) Current Transformers, precision PCB‑mount CTs, and ...

Würth Elektronik has expanded its free design tool REDEXPERT to include the Current Sense Transformer Selector. It allows developers to select the appropriate current sense transformers based on ...

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 ...
