Technical Q&A
Q: How to determine if the oil needs to be changed or filtered?
A: • Oil Quality Testing: regular checks for breakdown voltage, water content and acid value
• Visual Signs: darkened oil or the increase in suspended particles
• Insulation Failure: Determined through a withstand voltage test
Q: What protection devices are essential for the transformer?
A: •High Voltage Side: circuit breaker or fuse
•Transformer Protection: gas relay, pressure relief valve, oil temperature gauge
•System Protection: lightning arrester
•Monitoring Devices: oil level gauge, online oil chromatograph (premium models)
Q: How to handle oil leakage?
A: • Minor Leaks: tighten bolts or replace gaskets
• Severe Leaks: shut down the equipment, drain the oil, and repair or replace components
