Industry demand

Accurately and effectively detecting voltage, current, phase, and power and making adjustments are fundamental requirements for three-phase programmable power sources in the power industry. Stable current input and output are handled, and through software calibration, the output of AC/DC voltage, current, phase, and power is all highly accurate, addressing issues such as “virtual power” metering in the market.

Solution Objectives

To address the input and output issues of electrical energy from three-phase programmable power sources, Touch Vision has launched corresponding solutions. Power equipment can be automatically or manually calibrated, while multiple different experimental schemes are saved simultaneously; It can output a complete sine wave signal while precisely controlling the distortion of the sine wave; During performance testing or metering, actual AC power needs to be generated, and current, tension, and phase of any phase can be independently adjusted; It features multiple protection functions, including current limiting protection, high-temperature protection, voltage short-circuit protection, and current open-circuit protection, and can deliver highly stable output for fast and accurate detection and compensation.

Hardware composition

The three-phase programmable power source is a high-precision testing instrument that integrates electric meter calibration, electrical parameter testing, and detecting power quality issues such as waveform distortion, voltage fluctuations, and three-phase imbalance in the power grid. Mainly used for testing and verification of digital power measurement instruments, power sensors, power transmitters, and distribution automation terminal instruments. It features an intelligent host connected to a computer for operation, with a large LCD display.
