HVDC Contactors and Failure Modes

A useful Durakool technical presentation regarding correct and incorrect HVDC contactor positioning. Typically an electric vehicle (EV) will have two main contactors positioned in the feed from the battery to the electronic motor drive. There may be others used as part of the pre-charge, discharge or charging circuits. The principle function of the main contactors is...

Temperature & its effect on Electro Mechanical Relay Operation

A three page technical document highlighting how failure to understand or make allowances for the effects of temperature on electro mechanical operation can lead to the relay failing to operate when called to do so, or worse, the premature failure of the contacts! A much neglected and misunderstood area in the application of electro mechanical relays.
