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 ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

Megger’s new SMRT 36 smart protective relay test set is suited not only for testing today’s installations and legacy plant, but also for meeting the future challenges associated with testing the smart ...

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 ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...
