In many plants, the answer to that question is only a guess. That situation exists usually because management tries to “save money” on infrastructure maintenance.
The following tips allow you to have a more educated answer even if your budget isn’t realistic, and to perhaps increase that budget:
- Check circuit breakers to ensure the settings are where they are supposed to be. If the correct settings are unknown, that’s proof you need a qualified firm to assess your circuit protection strategy.
- If you have liquid-filled transformers, check the pressure gauge (it should be positive), trend the temperature, and inspect for leaks around the base. If you find a problem transformer, consider that good news because that’s your foot in the door for scheduled oil analysis.
- The “we’ve gotten by without it so far” excuse can prevent you from performing predictive maintenance (PdM), such as thermography or ultrasonic analysis. Have a qualified testing firm conduct the recommended testing (per IEEE 3007.2-2010) on critical portions of your distribution system as a pilot project.
