UNIVERSAL INPUT DEVICE FOR A TAP CHANGER |
摘要 |
A control system (10) providing a universal input (20) for receiving a control signal for actuating tap-changing equipment (40). The system (10) accommodates virtually any signal voltage level commonly used for control of the tap-changing equipment (40), modifies the received signal to a desired format, and inputs the modified signal to a controller (30) for decoding and actuation of the tap-changing motor. The system (10) is fully electronic, eliminating the use ofelectromechanical contacts for control of the tap-changer and providing a flexible approach to monitoring and diagnostics even from a location remote from the tap-changing equipment (40). |
