The Qualstik Plus is an excellent survey instrument for locating problem areas for comprehensive testing. It was developed specifically for the measurement of four important items of power quality: current, leading/lagging power factor, total harmonic distortion and the direction of current flow.
The live-line power meter isn't position sensitive; just slip it over a conductor and touch the electrode on the bottom of the sensor to the line. Your opening of the sensor isn't electronically closed and external currents are also electronically rejected.
The universal hotstick adaptor and internal structure of the Qualstik Plus are made of long glass fiber reinforced thermoplastic polyurethane. The housing is resistant to shock, water repellent, flame retardant and operates in a wide temperature environment.
The Qualstik Plus is an excellent tool for determining placement of power factor correction devices, survey primary lines for hamonic distortion...
