1. Introduction

    This series of transformer-type power sensors are composed of two types: master and slave. A single master is a single-phase power sensor; a master + a slave is a three-phase three-wire power sensor; a master + 2 slaves is a three-phase four-wire power sensor.

Power sensor is a device used to monitor the voltage, current, power, power factor, power, start waveform, running waveform, harmonics and other parameters of various types of equipment during operation, and predict the status of the equipment.

The existing equipment of the enterprise transmits the data to the main station through WiFi (if there is no ready-made WiFi network on site, the router will be built with a supporting WiFi to 4G router) The manufacturer can install the power sensor in the device. It supports the programmable logic controller (PLC) to read the sensor data through RS485 for application.
