Check Tool
The LineWatch® Check Tool is an integral part of the LineWatchM sensor installation. The Check Tool is a fully automated system designed to quickly and easily calibrate the sensors in the field with highly accurate voltage (0.1%) and phase angle measurements. The Check Tool can also be used as a precision stand-alone, quick reference tool for spot measuring phase-to-neutral voltage and phase current and power flow on a live line.
A patented capacitive voltage divider delivers unprecedented accuracy
Uses include:
• Measuring feeder primary voltage, current and power
• Troubleshooting distribution circuits
• Site survey for capacitor bank placement
Key Features and Benefits
