Typical System Layout

The UltraTEV MonitorTM is the product of EA Technologys unique experience as a pioneer in the measurement and interpretation of PD activity for over 50 years.

UltraTEV™ Cloud

Innovative and totally secure data access from the UltraTEV Monitor™ (available as an option), making costly site visits to view data unnecessary. Our innovative technology ensures that your latest data is always available to you online.

Product Options

Portable UltraTEV™ system:

  • for a smaller asset base
  • where flexibility of PD monitoring duration and positioning is key
  • for accessible sites

Wall-Mount UltraTEV™ system:

  • when monitoring multiple panels
  • for a permanent installation at a particular site
  • for accessible sites

UltraTEV™ Cloud with either the Portable or Wall Mount UltraTEV™ system:

  • where sites have poor or costly access
  • where good communication links are available and remote communications optimize site asset management

Valuable Condition Data

The ability to gather data on the condition of assets is a key part of the process of upgrading to Condition Based Risk Management™ (CBRM). This is EA Technology’s market-leading methodology of applying a Health Index to each asset, which includes the probability and consequence of its failure; an approach which is proven to improve asset reliability, availability and safety, whilst reducing the overall costs of asset maintenance and replacement.
