Operation and maintenance of Lightning Impulse Voltage Test Equipment
Keep generator and insulation surfaces clean to avoid dust accumulation.
Protect the equipment from moisture in operation and storage; ventilate and dry interior if ambient humidity is high.
Lubricate mechanical transmission parts after prolonged use.
Protect semiconductor coating on ceramic bushings; apply anti-corona paint if severe corona appears.
Stop operation and repair if oil leakage or abnormal noise occurs; return to service only after repair and verification.
On ignition-pulse malfunction, inspect for short/open circuits in the ignition system and rectify faults.
