Installation and Environmental Specifications

Compliance and Testing Standards

• IEC 60289: Reactors for AC power systems

• IEEE C57.12.01: Standard general requirements for dry-type transformers

• EN 61558-2-20: Particular requirements for small reactors

• Routine tests include:

• Impulse voltage withstand test (10kV peak)

• Temperature rise verification (Class F insulation)

• Partial discharge measurement (<10pC)

Maintenance Protocol

1. Quarterly: Infrared thermography of connections

2. Biannual: Insulation resistance test (5kV DC Megger)

3. Annual:

• Core bolt torque verification (35Nm ±5%)

• Winding resistance measurement

• Acoustic noise level validation

Safety Notice: De-energize and ground for 15 minutes before maintenance. Use CAT III PPE for 400V systems.
