| Attaching an electrical cable to the Robotron 50-kA high current source in preparation for an electrical safety experiment |
The Robotron 50-kA high current source is an electrical power supply capable of delivering up to 50 kA ac current with precisely controlled triggering and pulse duration. This power supply features a liquid-cooled transformer and a processor-based output controller. It has been used to examine the thermal characteristics of electrical conductors under short circuit conditions as part of research studying the performance and safety of mine electrical cables. It can also be used to study the performance of circuit over-current protection devices such as fuses and circuit breakers.
