Online Partial Discharge Monitoring System For Switchgear

MOEORW-W5086K Partial Discharge Online Monitoring System is developed for 10kV and above metal enclosed switchgears, fully compliant with international & regional power industry standards:

• IEC 60270:2000 Partial discharge measurements (core global standard for PD testing)
• GB/T 7354-2003 (equivalent to IEC 60270)
• Power industry technical specifications for TEV & ultrasonic PD detection

This dual-sensing system combines Transient Earth Voltage (TEV) + Acoustic Emission Ultrasonic two mainstream PD detection technologies recognized worldwide. All sensors are magnet-mounted, no drilling, no damage to switchgear insulation & sealing structure. Live installation without power outage drastically cuts on-site construction downtime for large-scale substation renovation projects.

Available in independent Ultrasonic sensor, independent TEV sensor, integrated TEV+Ultrasonic 2-in-1 sensor. Clients can match sensor quantity per cabinet based on project budget, effectively reduce overall procurement cost for large batches.

• TEV Sensor Technical Index (factory lab test data): Frequency range: 3 ~ 100 MHz (global standard TEV frequency band) Measuring range: 0 ~ 60 dBmV Resolution: 0.1 dBmV Linear error: ＜±20%
• Ultrasonic AE Sensor Technical Index: Detection frequency: 20kHz ~ 200kHz Measuring range: -20 ~ 70 dBuV Resolution: 0.1 dBuV Linear error: ＜±20%
   

2: High sampling accuracy for reliable PD diagnosis
125MS/s sampling rate, 14-bit high-resolution ADC module, collects 50 full power frequency cycles for comprehensive PD spectrum analysis (PRPD 2D / PRPS 3D mapping). Minimum detectable discharge magnitude: 5PC, ultra-high sensitivity to capture early insulation degradation signals before equipment failure.
 

3: Magnet mounting, zero wiring labor cost for mass installation
Built-in strong magnetic base, directly attach to switchgear cabinet surface without cable wiring, brackets or drilling. For bulk substation projects, installation labor cost can be reduced by over 60% compared with wired fixed sensors.
 

4: Wide harsh environment adaptability for global sites
Operating temperature: -15℃ ~ +60℃; Relative humidity ≤90%. Stable performance for tropical high-humidity areas, desert high-temperature zones, cold northern regions, underground compact substations. Built-in explosion-proof lithium battery, no external power wiring for each sensor, safe for enclosed switch rooms.
 

5: Strong anti-interference design for complex industrial sites
Adopts time-domain + frequency-domain dual digital filtering algorithm, separates industrial electromagnetic noise and real PD signals effectively. Withstands 600kV flashover impact without hardware damage or data loss, stable operation near transformers, high-current cables and frequency converters.

Intelligent Wireless Gateway (central data aggregation unit)

1: Multi global communication output for cross-region remote monitoring

Supports 4G cellular, WiFi, RS485, Ethernet, fiber optic multiple communication channels, compatible with local server monitoring platforms and cloud remote system, applicable for on-site local control & cross-country remote central monitoring for group power stations.

2: Distributed auto-networking, easy batch expansion

Plug-and-play distributed architecture, gateway automatically identifies newly added sensors without extra software configuration. Ideal for phased expansion of large power plants, industrial park substations, clients can purchase sensors in batches in stages without replacing existing gateways.
