6 FAQs about [Capacitor cable transfer inspection and repair]

What to do if a capacitor bank has an autotransformer?

If the capacitor bank has an autotransformer, check that it is in good condition and shows no signs of deterioration. Force the connection and disconnection of the capacitors in manual mode. (refer to the regulator’s manual before carrying out these actions) and perform the following checks.

What is a visual inspection of a capacitor bank?

Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.

How often should a substation and distribution capacitor bank be inspected?

The substation and distribution capacitor banks should be inspected and electrical measurements be made periodically. The frequency of the inspection should be determined by local conditions such as environmental factors and type of controller used to switch the capacitors on and off. 7. Visual Inspections

How to measure the capacitance of a capacitor?

Measure #1 – Verify proper mechanical assembly of the capacitor units, clearances as per the electrical code, and soundness of the structure of all capacitor banks. Measure #2 – It may be useful to measure the capacitance of the banks and keep the measurements as benchmark data for future comparison.

How do you check a capacitor bank after energization?

Also, measure and verify if the supply voltage, phase currents, and the kVAR of the capacitor bank are within the allowed limits. Approximately 8 h after energization, conduct a visual inspection of the bank for blown fuses, bulged units, and proper balance in the currents.

How do you test a capacitor?

Check that the capacitor current is not lower than 25% not greater than 120% of the nominal value by phase and that there is no phase unbalance greater than 15%. Carry out a dielectric rigidity test by applying 2.5 kV for 1 second between the terminals of the capacitor and earth. Check the capacity of the capacitors at the diferent steps.
