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

A transformer protection relay does not replace upstream devices. It defines responsibility. By clearly assigning fault ...

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 ...

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 ...

In continuing to provide the protective relay market with the newest innovations for replacement units, Basler Electric is offering a microprocessor-based BE1-50/51B-230 as an exact plug and play ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding interconnections, and increasing dependence on distributed energy ...
