Newnan, GA. Yokogawa Meters & Instruments Corp. has announced that it has developed the LS3300, an AC power calibrator that can accurately and stably produce a wide range of AC power outputs for the calibration of power meters and other types of power-measuring instruments. As it focuses exclusively on power meter calibration, the company said, the LS3300 will reduce the cost for the company’s customers.
Instruments used to calibrate power meters and power analyzers are capable of simultaneous voltage and current output with adjustable phase and can also perform three-phase AC power calibration if multiple calibration units are used in synchronization. These multifunctional instruments have a high price tag, are only capable of continuously outputting large currents for short periods, and are difficult to set up and operate for three-phase AC power calibration, Yokogawa said. As such, they do not meet the needs of customers who would like to calibrate smart meters and other power meters that require a large output current, calibrate single-phase AC power meters with a single unit, and easily and efficiently calibrate three-phase AC power.
In response to such needs, Yokogawa Meters & Instruments Corporation has developed the LS3300 AC power calibrator.
The LS3300 can calibrate AC voltage, current, and power as well as test both phase difference and power factor. While costing less than other calibrators due to focusing exclusively on power calibration, the LS3300 delivers a high accuracy of 0.045% and a superb stability of 0.01% per hour.
The LS3300 also includes as a standard feature the ability to output currents of up to 62.5 A for extended periods of time. Further, three LS3300s can be synchronized to output currents of up to 180 A, thus enabling the calibration of instruments such as smart meters and shunt-resistor current sensors and other devices that require higher currents.
One LS3300 unit can calibrate single-phase power meters. Multiple LS3300s can be used together to calibrate power meters used in single-phase three-wire AC power and three-phase AC power measurement. Using the multiunit control features of the LS3300, it is possibly to automatically set the voltage, current, power factor, phase, and other values on slave devices by updating those settings on the master unit. This reduces the amount of time needed for single-phase three-wire and three-phase AC power calibration.
Major target markets include government calibration laboratories, privately owned calibration organizations, and companies with departments that perform in-house calibration of power meters and other measuring instruments.
Companies that develop and/or manufacture measuring instruments such as power meters, clamp power meters, clamp testers, and smart meters are also potential customers.
