Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess the integrity of insulation in motors, cables, transformers, and other ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

The small, lightweight PTE-50-CE is the ideal instrument to test overcurrent and over/undervoltage protective relays, among many other applications. The reversible 100-VA amplifier can inject up to ...

AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...

“The HE-R2A relay series is suited for modern wall box designs, and we are happy that we can offer a UL508-compliant sibling of the HE-R type for European four-phase systems, enabling the ...

With its ease of configuration and its comprehensive range of facilities, including a variable-frequency voltage source with a continuous phase-shift function, Megger’s new self-contained SVERKER 780 ...

A motor protection relay safeguards electric motors by detecting thermal stress, phase imbalance, stall, and abnormal ...

The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a phase loss, phase reversal, phase unbalance, undervoltage or overvoltage condition ...

Relays are common electromechanical devices in electrical circuits that come in two types: either latched or non-latched. Latched relays retain their last switch position even after complete power ...
