Standard safety practices should be followed during installation, inspection, and maintenance of capacitors. Additionally, there are procedures that are unique to capacitor banks that must be followed to protect field operators and equipment in accordance with the NESC – National Electrical Safety Code.
Visual Inspection of Capacitor Bank Condition 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
Visual inspection of the capacitor bank must be conducted for blown capacitor fuses, capacitor unit leaks, bulged cases, discolored cases, and ruptured cases.
Why Test Capacitors Longevity: Testing helps detect early degradation, extending capacitor and device lifespan. Performance: Confirms capacitors are working efficiently, crucial for electronic circuit stability. Safety: Identifies faults that could lead to electrical hazards, protecting equipment and users.
The simplest way to test a capacitor is using a digital multimeter that includes a capacitance measurement setting. Here’s how to do it: Step 1: Disconnect the capacitor from its circuit to ensure an accurate reading. Step 2: Set your multimeter to the capacitance measurement mode (usually denoted by "Cap" or a capacitor symbol).
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.
