Installation, operation, and maintenance
- Installation guidance: Mounting orientation, clearances, earthing, and connection diagrams; observe polarity and phasing for correct metering/protection operation.
- Commissioning checks: Visual inspection, ratio and polarity checks, insulation resistance measurements, and functional verification with connected equipment.
- Maintenance: Periodic visual checks, terminal tightening, insulation resistance re-tests, and leakage/health monitoring for oil-filled units (dielectric tests, oil sampling).
