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 ...

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, ...

While capable of delivering 900 A continuously and 5,000 A for short periods, the new Ingvar primary current injection test set from Megger is readily portable, making it suitable for on-site use, ...

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, ...

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 ...

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.

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 ...

Here are the steps required to select the transformer and how to design the circuit needed to meet the end use in a manner that prevents transformer saturation Average current-mode control (CMC) ...

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...

In power supplies, dc-dc converters and many other power electronics circuits, chokes and transformers form an essential part of the filter network that provides low-ripple dc power. In many designs, ...

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 ...
