ST-702 satellite synchronous clock is a new generation of time synchronous clock in accordance with the "Technical Specification of Power System Time Synchronous System". It can not only provide high precision time synchronization signals for PMU, protection, measurement and control, intelligent terminal, fault recording and other plant terminal equipment, but also add a new multi-source selection mechanism about clock reference source. Remote online monitoring function and local log management function. ST-702 satellite synchronous clock can be widely used in power, energy, petroleum and petrochemical, steel, cement, equipment integration, municipal, security and other industries.

Intelligent computer harmonic elimination device can diagnose ferroresonance, but also can distinguish overvoltage, ferroresonance, PT high-voltage side break, PT low-voltage side break, single-phase grounding and other fault types; For ferroresonance of various frequencies, the information can be quickly eliminated and displayed. For overvoltage, ferromagnetic resonance, single-phase grounding and PT line break, alarm, and record and display. Suitable for electric power, metallurgy, coal, petroleum, chemical and other large enterprises, the device has superior performance, safe and reliable use.
