KEMA Labs Validates Critical Generator Switchgear

Ensuring grid resilience near generation hubs is crucial for every system operator. To guarantee that products perform reliably in real-world conditions, thorough testing under actual working scenarios is essential. This approach instills confidence in utilities regarding the operational reliability of their equipment.

A recent test involved a 24kV 10,000A 80kA Generator Switchgear, designed to protect power plants’ critical transformers against generating system failures. This critical piece of equipment underwent comprehensive type testing at KEMA Labs’ High Current Test Laboratory. The tests were conducted under real network conditions to ensure compliance with IEEE standard requirements, specifically IEEE C37.013 for the Vacuum-Generator-Circuit-Breaker.

The Generator Switchgear is intended for placement in parts of the grid with the highest rated current. A significant testing challenge was performing the temperature rise test at both 50Hz and 60Hz, necessitating a steady current supply of 10,000A and considerable space (nearly 30 cubic meters) for the test setup.

KEMA Labs’ High Current Test Laboratory is equipped to handle such rigorous testing, with capabilities to test equipment with continuous currents up to 50,000A and frequencies ranging from 15 to 65 Hz. This facility ensures that even the most demanding testing requirements can be met, affirming the reliability and safety of critical grid infrastructure components.
