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
Â
Type Tests to IEC ****6 (to be
done during acceptance testing at factory)
Â
• 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.
