Utilities in Saudi Arabia, the UAE and the wider GCC are expanding and modernising their networks. Online partial discharge monitoring, applied against IEC-based specifications and designed for desert conditions, is a key element of their asset management strategy.
High ambient temperature, humidity and condensation in tropical climates accelerate insulation ageing and drive partial discharge in switchgear. Understanding the mechanisms helps utilities in Southeast Asia choose the right sensors and monitoring strategy.
Power demand across Vietnam, Indonesia, Malaysia, Thailand and the Philippines is driving both new substation builds and rehabilitation of ageing switchgear. Online partial discharge monitoring is becoming the standard way for utilities in the region to manage insulation risk across a mixed fleet of legacy and new assets.
