Factory testing follows IEC/IEEE standards and includes routine tests (ratio, losses, resistance, impedance), insulation withstand tests, and sometimes temperature rise and PD tests. Commissioning on site includes oil sampling, grounding checks, OLTC verification, relay settings, SCADA integration, and thermal scanning before energization.
