Tap changer electric locomotives working on Indian Railways are provided with control based on electromechanical and Electro pneumatic relays/contactors. Such controls involve large number of interlocks, contacts, interconnections and cabling, which are not only maintenance intensive but are unreliable too. It was proposed to modify the existing electric locomotives by providing microprocessor-based control eliminating its hardware interlock. This is intended to primarily replace some of the existing conventional relays, reduce cabling and provide additional fault diagnostic information with improved overall reliability. The development of "Microprocessor Based Control and Fault Diagnostic System" for tap changer electric locomotives and its major objectives are as follows
