product name: ZK1501 generator low-light safety monitoring and early warning system
Product number: ZK1501
Product introduction:

ZK1501 generator low-light safety monitoring and early warning system is a system developed by our company to specifically detect, judge and warn the partial discharge between the generator rotor and the carbon brush in the slip ring chamber of the power plant. Easy operation and high reliability.

ZK1501 generator low-light safety monitoring and early warning system consists of ZK1500-II low-light sensor, ZK1501-I data processing unit and ZK1501-I display unit independently developed and developed by our company. It has monitoring arc light, liquid crystal display and mobile phone. The function of short message notification to remind the fault condition can monitor the arc light of the generator set, record the intensity of the arc light, and promptly alert in the form of liquid crystal display and short message.
