New gas sensors enable fault early warning for electrical equipment

New gas sensors enable fault early warning for electrical equipment

A high-tech enterprise has developed a new type of gas sensor suitable for electrical equipment. Based on nanomaterial sensing technology, this sensor can quickly detect multiple characteristic gases such as SF6 and H2, with a detection sensitivity reaching ppb level. When deployed inside equipment such as switchgear and GIS, it can real-time monitor the internal insulation status of the equipment and immediately trigger an alarm upon detecting abnormal gas concentration, providing an important basis for fault diagnosis of electrical equipment.

Mass production of low-loss voltage transformers, reducing power grid operating costs.

Mass production of low-loss voltage transformers, reducing power grid operating costs.

After years of research and development, an enterprise has achieved large-scale production of low-loss voltage transformers. This product adopts an amorphous alloy core and optimized electromagnetic design, reducing no-load current by 70% and iron loss by 60%. In power grid applications at 110kV and below voltage levels, it can save over 10,000 kWh of electricity per single device annually. The product has passed authoritative certification and will be widely applied in urban and rural distribution network renovations, helping to reduce the overall operating costs of the power grid.
