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.

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 ...

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

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 ...

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 ...

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 ...

Omron has introduced 400V and 600V 110°C versions of its G3VM photo mos isolated electronic relay family, as well as a 40V 2Ω type in the 1.5 x 2.5 x 1.3mm 4pin VSON package. With G3VM-401xY2 and G3VM ...
