Interlocking system for high voltage pulsed power laboratory / Wan Masniah Mohamed
The Pulsed Power Laboratory of Faculty of Electrical Engineering, ITM Shah Alam is operating without interlocking system. The tests done in this laboratory are not safe due to the voltage that can be produced by the equipment is up to 200kV and impulse current can be up to J 5kA. As protection again...

| Summary: | The Pulsed Power Laboratory of Faculty of Electrical Engineering, ITM Shah Alam is operating without interlocking system. The tests done in this laboratory are not safe due to the voltage that can be produced by the equipment is up to 200kV and impulse current can be up to J 5kA. As protection against electrical accidents, interlocking system is needed to cut off the high voltage power supply. Interlocking system comprising of sensor, controller and relay. Sensor is used to sense the opened door and is installed on the second entrance of Pulsed Power Laboratory and the relay served as a switch. The main objective of this project is to design the controller for the interlocking system, which is based on electronic circuit (replacing power circuit suggested by Kind [l]) to ensure the power supply of the high voltage system is still in off condition when someone opens second entrance of the laboratory. A DC power supply is designed and employed in the interlocking system. In this project two types of controllers, Delay Timer and Latch-up Switch are designed. However one controller is used at a time. |
