The Qualstik Power Quality Meter has been developed specifically for measurement of three important items of power quality in the electric utility industry. These are Current, True Power Factor, and Total Harmonic Distortion.
The Qualstik is an excellent survey instrument for locating problem areas for comprehensive testing. The SensorLink patented amp sensor does not use magnetic materials and has no moving parts. The opening of the sensor is electronically closed and external currents are electronically rejected. The True Power Factor is calculated by measuring the electric field in comparison with the current reported from the amp sensor.
The Qualstik is not position sensitive, just slip it over a conductor and touch the electrode in the bottom of the fork to the line. The meter will store and calculate the three measurements within 10 seconds. Return the instrument to eye level to view the measurements. The current reading is shown in one line of the display while the power factor and THD readings share the other line.
The housing of the Qualstiks are made of urethane and built to operate safely even in severe utility environments. They are resistant to shock, water repellent, and unsusceptible to flame. They also operate in a wide temperature environment.
The Qualstik is an excellent survey tool to assist determining placement of power factor correction devices as well as identifying other power quality problems.
The Qualstik comes in four different models. Two of these models make single sets of readings of current, power factor, and total harmonic distortion. The other two models offer the ability to measure current, power factor, and total harmonic distortion in multiple locations and save the readings for future review. The standard and wide jaw sizes of the sensor opening are available for both styles. |
