Substation Test Equipment

 

For utility and service companies, electrical maintenance testing is crucial for promoting and maintaining safety. New construction acceptance testing and existing substation maintenance testing are primary factors in prolonging the life of your electrical equipment and the ongoing reliability of a utility’s services to their customers. Routine testing of distribution, power, and instrument transformers, bushings, capacitors, circuit breakers, surge arrestors etc. can be accomplished by using Haefely / Tettex’s diverse line of test equipment.
