Application of Acrel ACR10R Series Intelligent Energy Meter with External Split Core CT in Chile Pump Station

1. Project Overview

Chile pumping station through the PLC system monitoring and operation, to achieve the unmanned duty. Since the customer requested to detect the power consumption of each water pump in the pumping station, the customer chooses the Acrel ACR10R series, the external transformer intelligent meter solution, using split-core current transformer and Simple DIN rail installation, Through RS485 communication docking PLC system linkage, real-time detection and upload power consumption data, easy to monitor and manage the pump station.

2. Product introduction

DIN rail multifunction electrical instrument with external Rogowski coil and split-core current transformer is applicable for the energy-saving reconstruction project in high energy consumption industries including the smelting, iron and steel, welding and semiconductor industry. It is also suitable for applications such as the power monitoring of grid-connected cabinets for distributed photovoltaic power cabinets and energy demand management. It boasts of no need for bus removal, easy connection and safe construction, saving reconstruction cost and raising efficiency for the user. It integrates the measurements of all-electric parameters (including single-phase or three-phase current, voltage, active power, reactive power, apparent power, frequency and power factor）and comprehensive energy monitoring and examination management. Meanwhile, it also has various peripheral interfaces for the user to choose from: the RS485 communication interface with Modbus-RTU protocol can meet the need of online communication management; the interfaces with switch input and relay output can realize the remote signaling and remote control of the circuit breaker switch. It is very suitable for a real-time power monitoring system with an LCD display and panel buttons to realize the setting and control of parameters
