An arc flash study is the evaluation of a facility to determine hazards in relation to the electrical system. The on-site study results in arc flash equipment labeling, fault current and coordination analysis, recommendations for improvement, and the required personal protective equipment needed to be worn.
Infrared thermal inspections of your Electrical Distribution System are an effective way to spot overloading and poor electrical connections without shutting down or stopping normal equipment operations. Early detection of problems allows for planned downtime and maintenance.
Ultrasonic testing uses ultrasonic technology to detect high frequency sound related to electrical discharges resulting from ionization of arcing, tracking and corona. This is an effective way to detect possible breakdown of the internal electrical connections in your electrical distribution equipment.
De-energized cleaning is a critical component to the overall maintenance program of your electrical distribution system. Regularly scheduled cleaning of your equipment gives you the opportunity to assess the condition and mechanical operations of each piece of equipment. This can help extend the life of your equipment and help avoid costly unplanned downtime.
Primary Injection Testing is accomplished by applying current to a breaker to check its electrical protection and mechanical operation. Circuit breakers that are part of a critical process are often maintenance tested using primary injection due to their high reliability requirements.
The purpose of secondary injection testing is to check that the protection scheme from the relay inputs are functioning correctly with the settings specified. This is achieved by applying an input from a test set to the inputs of the equipment relays and checking if the appropriate alarm/trip signals occur.
There are two methods for evaluating ground fault protection systems, by using simulated current at the relay or by high current primary injection testing. A trip and no-trip test shall be performed on the system ground fault equipment.
Annual preventative maintenance is proactive as opposed to a reactive approach to maintaining your electrical distribution equipment. This can help prevent unplanned outages due to electrical equipment failures and costly downtime.
