Overcurrent monitoring
WebOvercurrent and short-circuit detection and turn-off in a very short time period are becoming ever more important as the short-circuit withstand time of IGBT decreases down to 1 μs levels. Industrial motor drive reliability is strongly linked to the IGBT protection circuits. This article has outlined some approaches to handling this issue, and ... WebThese voltage-output, current-shunt monitors are commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits. The devices ...
Overcurrent monitoring
Did you know?
WebOvercurrent is used for automatic testing of directional and non-directional overcurrent relays with auto-assessment of the trip time characteristic, the directional boundaries of … WebLINETRAXX® CME420. The CME420 series current relays monitor undercurrent and overcurrent in AC systems as well as the current between two threshold values (window discriminator function). The currents are measured as r.m.s. values (AC). The currently measured value is continuously shown on the LC display.
