What Is TEV Testing?
TEV testing spots the silent warning signs of partial discharge—tiny electrical sparks that happen inside insulation or at connectors. These sparks can grow into major faults if ignored. Our friendly team uses handheld devices to scan your equipment externally, with no need to shut it down.
Frequently Asked Questions – TEV Testing
Q: What is partial discharge, and why should I care?
A: Partial discharge is a tiny electrical spark that occurs inside insulation or at points of weakness in high-voltage equipment. Left untreated, it can lead to equipment failure. TEV testing helps catch these sparks early saving you from costly downtime.
Q: Is TEV testing safe to perform while equipment is live?
A: Yes! Our TEV testing is completely non-intrusive and can be carried out safely while your equipment remains energized. No shutdowns or disruptions needed.
Q: How long does a TEV test take?
A: Most tests take just a few minutes per switchboard or panel. It’s a quick process that fits easily into routine maintenance checks.
Q: What happens if partial discharge is detected?
A: We’ll provide a clear, jargon-free report and walk you through your next steps. From pinpointing the issue to recommending further diagnostics or repairs, we’ve got you covered.
Q: What types of businesses benefit from TEV testing?
A: Any business using high-voltage switchgear—including manufacturing plants, data centres, hospitals, and utilities—can benefit from regular testing to reduce risk and ensure continuity.
