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.

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
