Tollgrade launches substation monitoring application

Tollgrade Communications Inc. has launched its new Substation Monitoring application to help electric utilities avoid some of the leading causes of preventable transformer failures.

The application is an addition to LightHouse, Tollgrade’s fault-detection and distribution monitoring platform. With the addition of substation monitoring, the platform enables utilities to have much greater visibility and reliability without installing costly backhaul communications like fiber optic lines.

Tollgrade’s LightHouse sensors have integrated communications, are hot stick deployable, and only take a few minutes to install. There is no need to roll fiber, de-energize substations or re-wire. Configurable alarms and reports allow utilities to know when transformers are being stressed by overloading or are in danger of aging prematurely due to unbalanced load.
