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.
Calibrations at frequencies from 50-400 Hz are avail- able over a more limited voltage range. The service for high-voltage capacitors provides measurements of capacitance and dissipation factor at applied voltages ranging from 100 V to 170 kV at 60 Hz depending on the nominal capacitance.
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.
Thermal Stability test 2. Measurement Of the Tangent of the Loss angle (Tanö) of the capacitor at elevated temperature 3. ÅC voltage test between terminals and container 4. Lightning impulse voltage test between terminals and container 5.
In making this evaluation, consideration must be given to the sensitivity of capacitor bank protection (such as unbalance protection) and the potential for a capacitor under test to inadvertently discharge stored energy into a protection system. In most cases secondary isolation of the protection system will be required.
It is therefore recommended that externally fused capacitors be tested before replacement in situations where the external fuse has blown. For internally fused capacitors, testing is required as the fuse is not visible. The following test procedure requires the capacitor/harmonic filter bank to be grounded and disconnected.
