Circutor CVM-A1500 - 3�3�- CVM-A1 X00-FLEX: ROGOWSKI SENSORS

The device must be connected to a power circuit that is protected with gL fuses (IEC 269) or
M fuses, with a rating of 1 to 2 A. It must be tted with a circuit breaker or equivalent device for
disconnecting the device from the power supply mains.
The power and voltage measuring circuit must be connected with cables that have a minimum
cross-section of 1mm
2
and the wires must to endure a temperature at least 77 degrees.
The secondary line of the current transformer will have a minimum cross-section of 2.5 mm
2
.
Current needs to be measured via external current transformers providing reinforced insulation.
3.3.- CVM-A1x00-FLEX: ROGOWSKI SENSORS
The CVM-A1x00-FLEX model measures currents using exible sensors, based on the Ro-
gowski coil principle.
The exibility of the sensor allows it to measure an alternating current irrespective of the posi-
tion of the conductor.
CIRCUTOR has a Rogowski sensor model that can be used with the CVM-A1x00-FLEX�
Table 5 shows the connection of the sensors and Table 4 the maximum position error.
