ACREL ASJ earth leakage relay’s Application in Philippine mine

Abstract: Ground fault protection for electrical circuits, equipment and electrical fire accidents caused by ground fault currents are increasingly becoming a daily necessity. For the main energy-consuming nodes on the user side, a residual current relay is designed and installed to monitor the residual current status of each energy-using circuit in real time. Through real-time monitoring of energy use and related power parameters, the safety, reliability and maintenance efficiency of energy use are improved, the labor cost of maintenance is reduced, and the unattended monitoring of residual current is realized. Through the real-time monitoring of energy use, data collection and alarm, the residual current in the power distribution system is monitored, and the ground fault protection of the user's electrical circuit is provided to prevent fire accidents and personal electric shock accidents caused by residual current. Here is a brief introduction to the application of our company's ASJ earth leakage relay in the Philippine mine.   1.Project Overview    The mine factory is located in the Philippines, because the current is very big, electricity supply for mine is special , customers hope that through in the power distribution ark installation of residual current relay to residual current monitoring line, and hope that can be displayed on the display panel real-time monitoring of residual current value rather than setting the ratio of residual current value, the ratio can reach 80% when the residual current relay immediately report to the police. Acrel ASJ10-LD1A with residual current transformer, successfully solve the customer's on-site residual current monitoring requirements. Due to the large current on site, we have communicated for many times on the selection of residual current transformer, and selected the most appropriate residual current transformer for the customer based on copper bar and current specifications.   ASJ Series Residual Current Relay     ASJ series current action relays can be combined with low-voltage power supplies or low-voltage contactor to form a combined power supply current protection, mainly used for AC 50Hz, voltage and below TT400V devices and TN system piping, in addition to ground fault protection for electrical circuits to prevent ground faults Common equipment damages and electrical failures caused by this can also prevent the danger of personal electric shock and provide direct contact protection.     The product meets the requirements of GB/T 22387-2016 "Catalyst Current Relay". ASJ series sanitary current relays integrate line over-voltage and under-voltage protection functions and automatic additional functions for normal voltage. The product is small in size, high in precision, flexible in structure and easy to install. It is a safety protection device in the field of civil construction   Model description Technical features Note 3：ASJ10L-LD1A rated residual action current I N is 10mA-30A continuously adjustable; Note 4：ASJ10L-LD1A limit non-driving Time N is 0-10S continuously adjustable.   Types of Products Note1：The function of setting for relay means that you can set the initialization and the output of the relay by yourself, which is acted by the dial switch on the panel; the specific setting guide can be found from the table 5.  Note2：OPTIONAL FUNCTION C: RTU Communication RS485, Model ASJ10L-LD1A/C Model Selection of Residual Current Relay 5.Installation picture Summary    ASJ series residual current relay has a very high performance-price ratio. As an advanced intelligent and digital residual current monitoring instrument, the residual current relay has been widely used in the incoming line or single-phase or three-phase of the household sub-box of civil buildings. Electric equipment in the power distribution line.    Bibliography 1.Solutions For Enterprise Micro-grid System 2021.04      

Application of Acrel Multi-Circuit Meter For Data Center In Thailand

Abstract:The quality of power supply in data center directly affects the operation of IT equipment, so IT is very important to monitor the incoming and outgoing lines of power supply in data center header cabinet. In addition, with the reduction of available energy and the increase of energy cost, how to use energy more economically and effectively has become the responsibility of relevant enterprises. 1. Project overview:     Data center power consumption multi-channel monitoring instrument, the series of monitoring instrument is mainly used in multiple distribution wire loop electric parameter monitoring, it will loop of busbar voltage, multiple matches out of the loop current, power, power and status of each circuit switching output concentration measurement, display, and communication, implementation of the monitoring requirements and simpler distribution wire loop measurement and monitoring.A customer of general contractor in Thailand purchased several sets of AC AMC16MA meters from our company, matched with his own touch screen, to meet the testing requirements of multiple AC circuits in data centers.The following is a detailed introduction to the AMC16MA  multi-loop meter 2.Technical Features   3.Network topology 4.Photo on-site Bibliography 1.Solutions For Enterprise Micro-grid System 2021.04
