| NIOSH engineer adjusts the voltage level on the Hipotronics 750-kVA three-phase and dc power source |
The Hipotronics 750-kVA three-phase and dc power source is a system that can supply electrical power at three-phase voltages up to 13,800 V, and dc voltages up to 700 V. Capable of delivering 750 kVA continuously, the system can supply 1.8 MVA for short durations. It has been used extensively in mine electrical safety research, such as in tests relating current to temperature rise on mine electrical cables, examining the deterioration of electric motors, developing techniques to distinguish between motor starts and short circuits, and evaluating protective relays and explosion-proof enclosures during simulated electrical faults.
