High-voltage switchgear and isolators must match the system rating and be type-tested. This guide covers the key checks when procuring them and their support structures.
Ratings and standards
Confirm voltage class, current rating and short-circuit withstand against the system requirement, and compliance with the relevant Indian/IEC standards.
Testing and approvals
Type testing (for example at CPRI) and utility approvals such as POWERGRID/discom specifications provide assurance of performance. ENSOL's power products are made to these requirements.
