Low voltage products - Predictive maintenance - 1

Low Voltage Products Predictive Maintenance Investing to prevent failures and their costly consequences, such as loss of production and possible violation of health and safety legislation, is a primary concern for many businesses. Successful prevention of failures can make a big difference but, to minimize maintenance costs, it must be optimized. Integrating the Predict feature into the ABB AbilityTM Electrical Distribution Control System (EDCS), ABB has created an easy-to-use tool to immediately understand, analyze and predict the health and status of monitored devices. A web page, accessible from anywhere, provides an overview of the health of all the devices monitored in the plant – and a detailed analysis of each device with a clear indication of a deadline (Next maintenance) for its next maintenance work. This date is optimized according to the real utilization of the device and its real environmental conditions. ABB Ability Electrical Distribution Control System (EDCS) is able to collect and analyze all the necessary data directly from the circuit breaker to define accurate mechanical and electrical aging trends. The number of operations, trips for overload (L ANSI 49), short circuits (S - ANSI 51 & 50TD, I - ANSI 50), earth faults (G - ANSI 51N & 50NTD), possible errors or Trip Unit malfunctions and all the environmental factors (temperature, humidity, corrosion, dust level and vibrations) are considered and used to calculate the circuit breaker’s working life. The device’s health conditions are represented with a color with a traffic light indication: the risk of a failure increases passing from green to yellow or orange or
