ROUTINE TEST to IEC 60076 (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 12 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 50%, 75%, 100% loading at unity p.f and rated terminal voltage (Corrected to 75C)
• Lightning impulse withstand test

11kv S11 Series three Phase Oil Immersed Distribution Transformer Instruction power transformer

The transformer is a transformer whose interior is isolated from the air surrounding, so the transformer oil can not absorb the outer moisture and the oxygen since the change of transformer's volume could be fixed with the flexibility of corrugated tank structure. Then the aging speed of insulated material will be decreased. Before running the machine, the work of core suspension checkup is not necessary. Clients could also be free from the later maintenance and reparation. The reliability of products is visibly upgraded. Products is designed with PCCAD, the characters are conformed to IEC 60076 and GB 1094, and passed qualification ISO 9001.

Characteristics

1. No devices like oil tank, and humidity absorber could assure the oil to be insulated from air and the oil could be used for 20 years consecutively without any treatment later

2. High qualified rubber used for the sealing

3. Oil filling in vacuum condition
