Why Southeast Asia Needs Partial Discharge Monitoring
Southeast Asia’s power grids are aging while renewable energy capacity expands rapidly. In tropical climates, high humidity and thermal stress accelerate insulation deterioration, making partial discharge (PD) one of the most common causes of switchgear, GIS and cable failures. HUWOR provides complete PD detection and online monitoring solutions — instruments, sensors and platforms — proven in high-voltage substations across China and ready to deploy in ASEAN markets.
Four Drivers of PD Risk in ASEAN Grids
- Aging infrastructure: many substations built in the 1990s and 2000s are approaching the end of their insulation service life.
- Tropical climate: sustained high humidity (60–90% RH) and temperature accelerate partial discharge activity inside switchgear.
- Renewable integration: large-scale solar and wind connection introduces harmonics and switching stress on existing switchgear and cables.
- Grid reliability mandates: utilities face growing pressure to reduce unplanned outages and move from time-based to condition-based maintenance.

Frequently Asked Questions
Which partial discharge detection methods do you support?
We support UHF, HFCT (high-frequency current transformer), TEV (transient earth voltage) and AE (acoustic emission) methods, following IEC 60270 principles for measurement consistency.
Can your sensors be installed on existing switchgear without a power outage?
Yes. TEV and UHF sensors are designed for live-line installation on existing metal-clad switchgear and GIS, with no outage required.
Do you offer OEM/ODM with custom branding?
Yes. We customize product specifications, branding, software platforms and packaging worldwide.
What is typical delivery time to Southeast Asia?
Standard products ship within 2–4 weeks from our Zhuhai and Xi’an facilities; OEM projects depend on configuration and are confirmed per order.
Do you provide training for local engineers and technicians?
Yes. We provide remote training, on-site commissioning support, and documentation in English.
Can your online monitoring system integrate with existing SCADA?
Yes. Our IoT gateway supports standard communication protocols (Modbus, IEC 61850 options) for integration with utility SCADA systems.
