APT Power Technology HV shunt capacitor bank is an extension to its main test system in those situations- huge capacitive compensation required. It can be used for: Induced voltage withstand tests on transformers and shunt reactors; Temperature-rise tests on transformers and shunt reactors;
The capacitor shall also withstand a 1 minute power frequency withstand test of a test voltage applied between the capacitor terminals and earth. For 12 kV rated capacitors, the test voltage is 75% of 28 kV. Refer to IEC 60871 or AS 2897 for other ratings. The requirements of the test are satisfied if no disruptive discharge occurs.
High fault current at capacitor bank primary connections. Stored energy in charged capacitors. For capacitors built to IEC 60871: Each capacitor unit shall be provided with means for discharging to 75V or less from initial peak voltage of √2Un. The maximum discharge time is 10 minutes.
Inspect the external surfaces and ensure the capacitor units and reactors are clean and dry. Check that primary connections are correct. Check earthing to capacitor bank mounting frames and enclosure. 5.6. Measure Insulation Resistance Insulation resistance tests as listed below are to be applied for one-minute duration each.
Note: The rated voltage (1.0~1.2)kV of the capacitor is special specification, the maximum customizable capacity is 40kvar. Y refers to star connection,N refers to null line lead out. Y refers to star connection,N refers to null line lead out. Y refers to star connection,N refers to null line lead out.
The capacitor bank can operate at 50 Hz and at 200 Hz. It operates at 200Hz for induced-voltage tests on transformers and shunt reactors; and works at 50Hz for Temperature-rise tests, measurements of load loss and short-circuit impedance. Take shunt reactor induced-voltage as an example.
