Can switchgear and distribution board maintenance move from a fixed interval to a condition-based check?

Partly: part of the task converts to a condition and part stays on the calendar. Temperature, discharge and operation count convert; the protection relay test and the internal clean and torque check stay on an interval set by the manufacturer and, for HV, by the network operator.

What condition would trigger switchgear and distribution board maintenance instead of the calendar?

Connection temperature rise, partial discharge activity above baseline (HV), breaker operation count reaching the maintenance count, contact resistance above the limit, or trip test result out of tolerance

What reading proves switchgear and distribution board maintenance was done?

Temperature rise per connection, partial discharge level, breaker operation count, contact resistance, protection relay trip time. Observed by: Thermal sensing or survey, partial discharge monitor on HV, breaker counter, micro-ohmmeter at the check.

What evidence does switchgear and distribution board maintenance produce for an ISO 55001 or ISO 45001 audit?

Maintenance record per board with the readings and the protection test results

Switchgear and distribution board maintenance

The board tells you its temperature and its breakers count their own operations. The relay test is the one thing nobody can monitor from outside and it stays.

asset class

Condition that replaces the interval: Connection temperature rise, partial discharge activity above baseline (HV), breaker operation count reaching the maintenance count, contact resistance above the limit, or trip test result out of tolerance
Reading that proves it: Temperature rise per connection, partial discharge level, breaker operation count, contact resistance, protection relay trip time
Why the interval stays: Temperature, discharge and operation count convert; the protection relay test and the internal clean and torque check stay on an interval set by the manufacturer and, for HV, by the network operator.
Evidence an auditor accepts: Maintenance record per board with the readings and the protection test results
First move: Fit temperature sensors on the main incomer terminations first; that is where the load and the consequence are.
