Tucson, Ariz. — C&D Technologies has introduced a new series of current sensing transformers designed to measure and monitor AC currents. Combining an isolation voltage of 500 Vdc and a primary ...

Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

Instrument transformers provide reliable and accurate input for the protection, control and monitoring of power grid assets such as motor control centers, UPS systems, utility metering, low and medium ...

A close collaboration with major transformer manufacturers has lead to the new Tettex 2796 Transformer Turns Ratio Meter. It combines mobility and user friendly handling with unmatched accuracy of up ...
