Transformer On-Load Switch Tap-Changer Analyzer
How to use this on-load tap-changer analyzer
Transformer on Load Tap Changer Test Equipment
The tap-changer contacts are tested for electrical continuity during tap-changing. By applying a constant current while tapping, the tester looks for open circuit transients during tap-changing. Bouncing or High Resistance Contacts cause arcing and possible tap changer or transformer failure if left undetected.
