secondary injection test kit is vital for testing the performance of a relay. A relay is a preventive switch which checks abnormalities in the flow of current. When sudden electrical charge flux is detected by a relay, it is important that the relay itself is kept in proper working condition. Leading electrical test tool brands like Megger and Doble specialize in manufacturing relay testing equipment and come up with devices that are always in top working conditions. Doble kit checks the condition of the circuit breaker, wear and tear the relay and the arrangement of all the relay parts.


Apart from the injection kit, a Megger digital low resistance ohmmeter tests lapses in resistance of the relay and the current operated device. This ohmmeter is capable of storing a large volume of resistance reading and can be used for comparing abrupt or noticeably low resistance readings with a standard reading. Often the relay insulation gets damaged and electrical charge dissipates. To prevent charge wastage, a relay should undergo regular tests for insulation and resistance.  

Doble relay is undoubtedly one of the best relay arrangements available on the market today. It is synonymous with a superior circuit break function and higher resistance cover. A relay from Doble prolongs the life of any electrically operated gear.
