Recently, a batch of products for a GIS Partial Discharge (PD) Online Monitoring Project completed final inspection and was successfully shipped from Zhuhai Huawang Technology. The shipment includes UHF partial discharge sensors and contact acoustic emission (AE) sensors, which will be installed as part of a GIS online monitoring system. Before delivery, all products underwent […]

Zhuhai Huawang has recently completed the shipment of a batch of ultrasonic inspection devices for power equipment inspection applications. As power systems continue to expand, utilities are placing greater emphasis on preventive maintenance and live-line inspection. Equipment such as switchgear, transmission lines, ring main units, and substations may gradually develop insulation aging, loose connections, or

Recently, Huawang successfully completed the shipment of a switchgear partial discharge and temperature online monitoring project for power equipment condition monitoring applications. The project includes: The system is designed to provide real-time monitoring of partial discharge activity, equipment temperature, and environmental conditions, helping improve the safety and reliability of power systems. 4-in-1 Partial Discharge Sensor for

Partial Discharge (PD) is widely recognized as the primary precursor to catastrophic insulation failure in high-voltage power cables. To mitigate the risk of unplanned outages and equipment explosions, proactive monitoring is essential. We are proud to announce the successful delivery of a new batch of High-Frequency Current Transformers (HFCT), specifically designed for online PD monitoring

Our latest partial discharge (PD) online monitoring project for a substation has successfully completed all stages of production, functional testing, and quality inspection. The entire system—consisting of high-frequency current sensors, ultrasonic PD sensors, IED concentrators, and accompanying accessories—has now entered the shipment phase and will soon arrive on site for installation. Strict Quality Control to

Our latest production run of digital leakage-current transmission meters—used for surge arrester online monitoring in substations—has now been completed and is on its way to project sites across multiple regions. These meters provide continuous, real-time visibility into the condition of substation surge arresters by tracking key parameters such as leakage current and operating status. The

Zhuhai Huawang Technology has successfully won the bid for the “Overhead Power Distribution Ultrasonic Live Inspection Framework Project” of Shenzhen Southern Power Grid Deep-Hong Kong Technology Innovation Co., Ltd. This achievement highlights Huawang Technology’s strong technical expertise and outstanding reputation in the fields of power equipment inspection and partial discharge (PD) detection. The successful bidding not only recognizes

As power systems become increasingly complex, the insulation health of switchgear, ring main units (RMU), gas-insulated switchgear (GIS), transformers, cables, and overhead lines has become a critical indicator for operation and maintenance. Partial discharge (PD) is an early warning sign of insulation aging and potential equipment failure. Early detection of PD is vital to prevent
