HV PROTECTION AND GRADING

Protection schemes are designed to detect any stress on a power system and automatically initiate predetermined corrective actions to prevent safety hazards and facilitate business continuity.

Our expertise encompasses protection scheme design, configuration and file loading into the relays. Full scheme testing is conducted during commissioning by our specialist commissioning team.

HIGH VOLTAGE SWITCHING

HV switching requires careful planning to ensure the safety of plant and people, while minimising disruption to business operations.

We analyse your system, drawing on our knowledge and experience, to establish the switching sequence required for an effective isolation.

Our experienced HV operators perform the switch according to the sequence and issue access permits when the area is safe.
