- 警報節點:
-
- The UltraTEV Alarm™ provides simple, low cost, continuous monitoring of substation switchgear. EA Technology’s UltraTEV Alarm™ can identify faults and safety issues BEFORE they lead to failures making it the Partial Discharge (PD) activity early warning system that businesses cannot be without.
- Benefits:
- Early warning of faults prevents failures
- Enables timely interventions when maintenance is required
- Warns personnel if switchgear is in a dangerous condition
- Excellent cost/benefit justification
- Features:
- Effective continuous monitoring with both ultrasonic and Transient Earth Voltage (TEV) sensors
- Multi-node sensor units can monitor 100+ assets simultaneously
- Receive alerts anywhere, via email or text message
- Simultaneously measures local humidity and temperature conditions
- Central Hub unit LED indicators provide immediate indication of PD problems
- Operation:
- Measure the surface activity using the ultrasonic mode, and compare the result with those taken from other similar assets
- Listen to the surface PD activity from the audio output (the system heterodynes the ultrasonic signal for this purpose)
- Nodes are linked to the Alarm Hub which indicates when PD activity in one or more assets is at critical level
- LEDs on the individual sensor nodes indicate which assets are affected
- Audible/visible alarms can be mounted outside the substation for added safety
- Ultrasonic Contact Probe detects PD activity in sealed cable boxes
- Can be used as a portable system or installed permanently
