Multi-Range Current Applications

3kV Winding Configuration Options

Parallel Connection

• Higher current capacity

• Reduced voltage per winding

• Ideal for high-load industrial sites

Series Connection

• Increased voltage handling

• Lower current flow

• Suited for transmission applications

Note: Configuration change requires certified technician

Installation Requirements

Compliance and Testing

• IEC 60289: Reactors for AC power systems

• IEEE C57.12.01: Dry-type transformer requirements

• EN 60076-11: Dry-type transformers

• Standard tests include:

• Temperature rise validation

• Impulse withstand (10kV)

• Partial discharge (<10pC)

Maintenance Protocol

1. Monthly:

• Visual inspection of cooling fins

• Thermal scan of connections

2. Quarterly:

• Insulation resistance test (5kV Megger)

• Winding resistance measurement

3. Annual:

• Full calibration of current ranges

• Dielectric absorption test

• Acoustic noise verification

Safety Notice: De-energize for 20 minutes before servicing. Use CAT III PPE for 600V systems.
