Maintenance Procedures
Taking care of your capacitor banks helps you avoid problems and keep your system working well. You need to follow a few important steps during maintenance of capacitor banks. Each step helps you find issues early and keep your equipment safe.
Infrared Imaging
You can use infrared imaging to spot hot spots in your system. This tool shows you where heat builds up. Hot spots may mean loose connections or failing parts. You should scan all units and cables. If you see a bright area, check it right away. Infrared imaging helps you catch problems before they get worse.
Tip: Schedule infrared scans at least twice a year. This helps you find hidden issues early.
Current & Capacitance Tests
Testing current and capacitance tells you if your capacitor banks work as they should. Use a meter to measure the current flowing through each unit. Compare the readings to the values in your manual. If you see a big difference, you may have a faulty unit. You should also test the capacitance. This shows you if the capacitors still hold enough charge. Low capacitance means you need to replace the unit.
| Test Type | What to Measure | What It Means |
|---|---|---|
| Current Test | Amps per unit | Checks for faults |
| Capacitance Test | Microfarads (μF) | Shows charge capacity |
Connection Tightness
Loose connections can cause overheating and failures. You need to check all bolts, screws, and terminals. Use a torque wrench to make sure each connection is tight. If you find a loose part, fix it right away. Tight connections help your system run safely and smoothly.
Check all terminals for looseness.
Tighten bolts and screws to the right level.
Inspect for signs of corrosion.
Documentation
You should keep records of every maintenance step. Write down the date, what you checked, and any problems you found. Good documentation helps you track changes over time. If you see the same issue often, you can fix it before it causes trouble. Use a simple logbook or a digital file.
Note: Clear records make future inspections easier and help you plan repairs.
Regular maintenance of capacitor banks keeps your system safe and efficient. You protect your investment and avoid costly downtime.
