ROUTINE TEST to IEC ****6 (to be done during acceptance testing at factory)
 
• Measurement of winding resistance
• Ratio test
• Vector group
• Separate source voltage withstand test
• Induced over-voltage
• Insulation resistance
• Oil leakage test on fully assembled transformer for *2 hours
• Measurement of impedance voltage
• Magnetic balance
• Measurement of no-load loss and current
• Measurement of load loss (at normal & extreme taps)
• Tests on on-load tap-changer
• Tests on on-load tap-changer remote control panel
• Efficiency at *0%, *5%, **0% loading at unity p.f and rated terminal voltage (Corrected to *5C)
• Lightning impulse withstand test

Type Tests to IEC ****6 (to be done during acceptance testing at factory)
 
• Temperature rise test – To be performed on one unit during acceptance testing.
Lightning Impulse Withstand Test is already listed under Routine Tests as per IEC ****6.
