Low Voltage Market Applications

Theft Detection/Anomalous Usage

Identify, reduce and eliminate power theft by deploying sensor technology as an energy balancing tool identifying losses, interruptions and malicious usage.

Grid Automation

Enable remote monitoring and operation of grid infrastructure for more efficient and automated management of the grid avoiding operational costs.

Voltage and Power Measurements

Improve efficiency of the distribution grid by monitoring voltage, current, real and reactive power. Voltage and current waveforms are captured and processed by an integrated microprocessor, providing detailed power quality information.

Fault Detection and Outage Management

The sensor system features outage ride-through super capacitors in order to supply last gasp messages. This allows for easy identification of the location of a fault to quickly restore power.

Asset Management

Asset monitoring for improved management and allocation of capital expenses.

Green Energy/Renewables Integration

Distributed generation interconnection permitting and ongoing monitoring.

LineWatch Medium Voltage

LineWatch M delivers near revenue grade (0.5%) current and voltage accuracy to address a variety of utility applications. The “bird-on-wire” design supports fast and safe hot stick installation greatly reducing deployment expense and total cost of ownership. LineWatch incorporates a flexible design that supports any utility communications platform.

Features and Benefits

LineWatch Low Voltage
  • Remote monitoring and grid infrastructure
  • No neutral connection
  • Safe and easy installation
  • Continuous monitoring
  • Reduces power theft
  • Compatible with any utility comm platform
  • Power quality measurements up to the 13th harmonic
  • User configurable alarms/events
  • Flexible reporting tools
  • Reduces operating costs
  • Identifies faults for quicker power restoration

Medium Voltage Market Applications

Legacy Substation Monitoring

Monitoring of assets located at substations without need for costly renovations or service interruptions

Grid Automation

Enable remote monitoring and operation of utility infrastructure for more efficient grid management

Volt/VAR Optimization

Sensors can be used as part of a centralized VVO system or locally as replacement of PTs or line post sensors

Fault Detection and Outage Management

Easily identify the location of a fault for quicker power restoration

Asset Management

Asset monitoring for improved management and allocation of capital

Voltage, Current and Power Measurements

Voltage, current, real and reactive power monitoring to support power flow studies and modeling

CheckTool Medium Voltage Installation

LineWatch Check Tool is an integral part of the LineWatch M sensor installation. Its highly accurate voltage and phase angle measurements are used to quickly and easily calibrate the sensors in situ.

0.1 accuracy class spot measurement of voltage with current and power

LineWatch Check Tool is an integral part of the LineWatch M sensor installation. Its highly accurate voltage and phase angle measurements are used to quickly and easily calibrate the sensors in situ.

The Check Tool can also be used as a precision stand-alone, quick reference tool for spot measuring phase-to-neutral voltage, phase current, and power flow on a live line. Unlike the LineWatch M product, the Check Tool is not intended to be left on the line.

Benefits

  • Quick and easy sensor calibration
  • Most accurate hot stick power meter on the market
  • Measures real and reactive power flow
  • Measurement of live line conditions
  • Can log measurements to local file
  • No need for multiple tools
