Transmitter intended for direct measurement of high DC voltages in the range ±100 V to ±3600 V, covering all standard DC traction voltages: 750 V, 1500 V and 3000 V. 3600 V AC/DC insulation with a 15 kV AC test provides the required safety margin against switching overvoltages characteristic of traction networks. The device is factory calibrated and range-selectable, reducing commissioning time for measurement installations in new and modernized substations.
