Preventative maintenance Protection Data collection Continuous monitoring of residual current has proved to be an effective method of maintaining preventative maintenance systems. The result of monitoring the electrical network is a more reliable and “cleaner” electrical system. Continuously monitoring units detects faults and generates alarms for the following: • insulation damage or degradation • wiring errors • neutral-to-ground faults • connection of defective devices • leakage currents insufficient to blow a fuse or to trip a circuit breaker. Residual current is measured by a sensitive sum...

Remote/stand-alone monitoring system Warning Alarm Internet Ethernet Warning Alarm Warning Alarm

With a VRE device equipped with the Master functionality, you can see at one glance the status of totally 32 VRE devices at maximum. Via the Internet, you can control all your VRE devices from anywhere using any computer equipped with a web browser. On the main view of a VRE device you can see the status of all channels of the device. The colour of the channel cell tells the alarm status of the channel, so here you can see at one glance the channel which has caused the possible alarm. The colour of the device cell tells the alarm status of the device. You can view the channel-specific information...

Single channel Residual Current Monitoring System Technical summary Digital display of current and set values Measuring range: Model VR-16 DIN opening in panel boards Flush mounting with mounting kit DIN 35 rail IP 54 (Nema 4) window for flush mounting Automatic self-testing The benefit of using earth leakage current monitoring system is having a better personal and fire satety. Insulation faults can be predicted and preventative maintenance can be done in time. Ground fault protection can be used for equipment protection only - not for personal protection. Residual current monitoring. Also available...
