“Veridian’s diverse service area poses multiple challenges for fault identification and power restoration because the majority of the communities we serve are non-contiguous and many are in very rural areas. Before LightHouse we had to rely on line patrols or Fault Current Indicators (FCIs) and had very little visibility at rural substations,” said Mark Turney, the utility’s Vice President of Operations.
Now with LightHouse, we have a safe, maintenance-free solution that provides real-time data reliably at a fraction of the cost of alternatives. LightHouse allows us respond to outages and restore power faster.
“Veridian is one of the unsung heroes of grid modernization showing utilities how next generation technologies like Smart Grid Sensors can be used to more affordably retrofit intelligence into the distribution network,” said Edward H. Kennedy, President and CEO, Tollgrade Communications, Inc. “Our work with Veridian proves how easy the integration of LightHouse into Supervisory Control And Data Acquisition (SCADA) systems can be.”
In 2013, Veridian turned to Tollgrade’s LightHouse platform because it was a safe, maintenance free solution that could reduce Operations and Maintenance (O&M) expenses plaguing traditional fault detection methods, for example:
Unlike FCIs, LightHouse Sensors are inductively powered (battery-free), with a lower Total Cost of Ownership (TCO) over their 20 year lifespan
Unlike FCIs, LightHouse sensors have integrated communications and fault analytics software for better data accuracy, are remotely configurable and firmware upgradeable
Tollgrade’s LightHouse system feeds data directly into Veridian’s SCADA systems using the Distributed Network Protocol (DNP). A single SCADA screen is now used to view all field sensors, their alarms for permanent and momentary faults, and their loading data. Veridian is now able to identify fault type and to get visibility at their rural substations by aggregating load information from their feeders and substation transformers.
Using the “predictive grid” or analytical software features available in LightHouse, Veridian can start identifying the root causes of problems so that they can manage their system in the most optimal way. LightHouse possesses a unique ability to capture waveforms so engineers can analyze events in their network. By providing waveforms to better understand the nature (and location) of faults, Veridian’s distribution engineers can more proactively respond to outages and momentaries.
From an asset management perspective, Veridian also found LightHouse particularly useful as a substation monitoring solution. The LightHouse Sensors are deployed in Veridian’s rural substations where there are no breakers and relays for monitoring and control. The platform enables Veridian 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 enable Veridian to know when transformers are being stressed by overloading or are in danger of aging prematurely due to unbalanced load.
Demonstrations at IEEE PES Transmission & Distribution Conference & Exposition 2014. Tollgrade will demonstrate the LightHouse platform and their newly announced MV Power Sensor –the industry’s first battery-free, hot-stick deployable Smart Grid sensor that provides accurate voltage and current measurements in a form factor requiring no pole mounted equipment. Visit Tollgrade in booth #2418 for a demonstration.
