Keedian operations · Standard procedure
Sustained undervoltage.
Service voltage sits below the lower band for several intervals — chronic undervoltage overheats motors and shortens their life.

- Preconditions
- Voltage telemetry at the service; nominal band on file.
- Human role
- Files the utility / power-quality claim and pre-empts equipment damage.
- Action plan
-
(1) Confirm RMS voltage below the lower band (ANSI C84.1 Range B ~ -8.3% / EN 50160 -10%) for 3+ consecutive intervals.
(2) Notify the utility — the service / transformer / neutral is their responsibility; log a power-quality claim.
(3) Expect elevated motor current → schedule a compressor check before burnout.
- Escalation
-
(1) Voltage event correlated with an equipment trip → attribute to power quality vs internal fault to avoid a wasted diagnostic truck roll.
(2) Recurring undervoltage → push the utility on the service.
- Prevention
-
(1) Track voltage band-compliance per site; raise chronic issues with the utility proactively.
