Not calibrated EM010 traction voltage sensors
EM010 from 2000 to 5000 V
| Utilisation Sensors to measure d.c. or a.c. currents with a galvanic insulation between primary and secondary circuits.Warning: The voltage UP to be measured cannot be directly applied to the primary terminals marked «+» and «-» for not calibrated EM010 sensors.In order to use these not calibrated EM010 sensors for voltage measurement, an input resistance RE must be added to the primary (see diagram below). The voltage rating is determined from the value of this resistance RE (refer to calculation examples at the end of this catalogue). |  |
