  • Warns of developing faults BEFORE they lead to failure
  • Instant alerts if switchgear warrants investigation
  • Protects production-critical assets
  • Peace-of-mind assurance that switchgear is working properly
  • Continuous safety monitoring protects personnel
  • Excellent cost/benefit justification


  • One Alarm Hub can monitor 100+ assets simultaneously
  • Accurately calibrated to avoid false alarms – and identify real faults
  • Audible/visible alarms can be mounted outside the substation for added safety
  • GPRS-enabled Alarm Hub option sends SMS text message or email alerts to operatives automatically


The UltraTEV Alarm™ is simple to install and completely automatic in operation. It provides instant alerts if PD activity reaches a potentially damaging level. Just as importantly, it provides continuous assurance when production-critical assets are operating correctly.

The system can be fitted temporarily or permanently in a range of configurations e.g. the hub and visual/audible alarms may be fitted outside a substation to alert personnel to possibly dangerous PD activity.
