Electric Substation Termography - Frequency
Electric Substation Termography - Frequency
(OP)
G'day All,
Is there any method (or industrial standards) of establishing how often electrical substations (MCC and HV Switches) should be surveyed for faults using Thermography?
We traditionally used to check them every 12 months. Should we move to 6-monthly intervals or stay at 12?

Are there pre-conditions that can be spotted?
The answers to these questions should be part of your decision process

I major lesson I have learned is to reinspect the equipment after repairs have been made. I did not do this at first and found that the same items were coming up on every survey. We were having a sucessful repairs only 50% of the time. After working with the electricians during the repairs the success rate is now 95+%.

Now, after all those repairs, once a year cycle is sufficient.
God bless!
