Tollgrade LightHouse® Medium Voltage (MV) Power Sensor 

First battery-free Smart Grid sensor measuring voltage with 0.5% accuracy

Your distribution network is the backbone of electricity delivery and is often the largest unmonitored part of the grid. Without visibility, how will you handle 21st century distribution challenges? Tollgrade LightHouse MV Power Sensors provide a new generation of distribution monitoring with the real-time actionable intelligence you need to monitor and optimize power conditions and improve reliability.

Accurate Voltage and Current Measurements that Seamlessly Integrate with Your DMS

High accuracy voltage and current measurements provide valuable real-time inputs to key planning models and control applications.  Interval data logging, remotely configurable alarm thresholds, and waveform capture provide comprehensive visibility of grid conditions and events.  Data and alarms can be accessed via reporting and graphing tools in the LightHouse Sensor Management System (SMS) software, or can be integrated via DNP3 to other back-end systems such as SCADA, Data Historians, Energy Management Systems (EMS), and Distribution Management Systems (DMS).  MV Power Sensors provide key inputs to a wide range of applications including:

  • CVR and Volt/VAR Optimization
  • Enhanced Substation Monitoring
  • Distributed Generation (DG) and DER Integration
  • Enhanced DMS Powerflow Modeling
  • Power Quality Monitoring
  • Reliability, Fault Notification and Location
  • Voltage Regulator Monitoring

Half the Cost of a Line Post Sensor Solution

Our MV Power Sensors are designed to be an affordable turnkey solution.  A single crew can install a set of sensors within minutes.  Sensors are safely installed with a hot stick or insulated gloves, with no calibration required – ever!  Clamp-on line sensors with integrated wireless communications avoid the installation time, pole clutter and recurring field calibration associated with line post sensors, optical sensors and pole-mounted meter cabinets.  Sensors are inductively powered to eliminate the costs of expensive battery maintenance. Finally, all sensors are remotely configurable and integrated with our LightHouse SMS software with Predictive Grid® Analytics. When you combine all of these benefits, Tollgrade offers the lowest total cost of ownership.   With the simplicity and all-in-one integration of the LightHouse MV Power Sensor, monitoring your network has ever been so simple and cost effective.

Safe and Reliable Voltage and Power Measurements

The LightHouse MV Power Sensors are easily installed on MV conductors and directly connected to system neutral, pole ground, or non-loadbreak cutouts via light gauge copper wire. LightHouse MV Power Sensors utilize an internal voltage divider to provide measurements of feeder voltage and safely maintain system insulation.  Sensors are tested to meet comparable surge and insulation standards as line post sensors and surge arrestors.

Flexible, Ubiquitous Communications Options

LightHouse supports a wide range of communications options. Our cellular MV Power Sensors include 3G communications for high speed real-time reporting of events and data.  Sensors can be quickly installed, automatically power up, connect to the network and back office. Where other smart grid communications networks are used, our Wi-Fi MV Power Sensors support easy integration with public and private IP-based networks via LightHouse Aggregators or third party communications nodes.
