Installation & Operation

1. Mounting: Install on level concrete pad with vibration isolators

2. Oil Management:

• Maintain oil level 50mm below conservator neck

• Check silica gel in breather (blue indicates dry)

3. Electrical Connections:

• Use 185mm² minimum cross-section cables

• Apply antioxidant compound on busbar joints

4. Safety: Grounding resistance ≤4Ω

Maintenance Protocol

• Daily Checks: Oil level, breather color, abnormal noises

• Quarterly:

• Oil sample analysis (BDV >50kV)

• Torque verification on bushing connections

• Annual:

• Insulation resistance test (5kV DC minimum)

• Contact resistance measurement on tap changers

Compliance Standards
