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 ...

Testing relays is both an art and a science. As relay technicians inevitably learn in the field, pure theory-based understanding of protective relays is not nearly enough for the real-world situations ...

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.

Protective relay installations that are based on IEC 61850, the international communication standard for electrical substations, can now be tested with Megger’s MPRT test set. The IEC 61850 option ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...

An 8 Gbps high-speed relay MMIC for an Automated Test Equipment (ATE) using a gallium nitride is developed and evaluated. Metal-Insulator-Semiconductor structure with a tantalum oxynitride is employed ...
