Experience from Pilot Implementation of Substation Inspection Robots in Thailand’s High Voltage Substations

As part of the effort to digitalize substation equipment inspections, a transmission system utility in Thailand carried out a pilot project using substation inspection robots at two high voltage substations. The main goal was to increase the frequency of routine visual and thermal checks, reduce the time field operators spend on manual inspections and report writing, and build a more detailed and frequent dataset to support future condition-based and predictive maintenance.
