SF6 Decomposition Products Detector
JH4000A-4 SF6 Electrical Equipment Decomposition Products Detector is a high precision, intelligent and portable device, able to make judgment rapidly and correctly based on the content of main decomposition products of insulation materials inside the SF6 electrical equipment like SF6 circuit breaker, instrument transformer, GIS and transformer. It detects SO2+SOF2, H2S, CO and HF. It is reliable, accurate and stable. Inspected by authorities such as the National Institute of Metrology, the device, having excellent performance, complies with relevant international and national standards. It is a product recommended for use by the State Power Grid Company. Decomposition products detection provides reliable evidence for the internal fault diagnosis and it is an effective measure for preventive and corrective maintenance.
