- Type A: Side-mounted design, with mounting holes on the core clamp
- Type B: Base-mounted design, with an integrated mounting base for enhanced stability
- Altitude: ≤3000 meters
- Ambient Temperature: -5°C to +40°C
- Relative Humidity: ≤85% (at 20°C)
- Installation Environment: Free of corrosive gases and conductive dust
- Pre-Operation Inspection: Perform routine tests including polarity verification, connection group check, insulation resistance measurement, and phase sequence confirmation before commissioning.
- Wiring Requirements: The primary winding must be connected in parallel with the circuit under test; the secondary winding must be connected in parallel with measuring instruments or protection devices, with correct polarity.
- Load Limitation: The secondary load must not exceed the transformer’s rated capacity to avoid increased measurement errors.
- Secondary Circuit Protection: The secondary winding must not be short-circuited. Install secondary fuses to prevent equipment damage from short-circuit currents.
- Safety Grounding: The secondary winding must be grounded at one point to prevent high voltage exposure to operators in the event of insulation failure.
