Omicron’s new Votano 100 is the first voltage transformer testing and calibration system to combine mobility (total weight less than 33 lbs /15 kg) with the highest level of accuracy (precise ...

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.

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

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) ...

In switched-mode power supplies (SMPS), magnetic components, namely inductors and transformers, play critical roles. Much of the SMPS design process relies on component specifications and simulation ...

Each turbine in a wind farm is equipped with a step-up transformer, which boosts (steps up) turbine generator output voltage from a few hundred volts to the collector system’s medium voltage ...

People can thank voltage transformers, a kind of instrument transformer, for decreasing voltage intensity to safe levels and subsequently transporting the reduced power to homes. Transformers, which ...
