5.2.3.4 Temperature

For V, U, I, P, Q, S, FP and E:
■
300 ppm/°C, with 5% < I < 120% and PF = 1
■
500 ppm/°C, with 10% < I < 120% and PF = 0.5 inductive
■
Typical DC offset V: 10mV/°C

5.2.3.5 Common Mode Rejection

The common mode rejection ratio on neutral input is typically 140 dB. For example, 110V applied on the neutral input will
add 11µV to AmpFlex /MiniFlex
®
will add 11µV to other current sensors' values, resulting in an additional error of 0.01% Inom.

5.2.3.6 Magnetic Field Influence

For Rogowski inputs (without sensors): 10 mA/A/m typical at 50/60 Hz.

5.2.4 Current Sensors

5.2.4.1 Precautions for Use

Refer to the safety sheet or user manual that was supplied with your current sensors for more information.

5.2.4.2 Use and Characteristics

Current clamps and flexible current sensors are used to measure the current flowing in a cable without opening the circuit.
They also insulate the user from dangerous voltages in the circuit.
■
The choice of current sensor to be used depends on the current to be measured and the diameter of the cables.
■
When installing current sensors, face the arrow on the probe or the sensor in the direction of the load.
