Limits of the AmpFlex
®
and
MiniFlex
®
Like all Rogowski probes, the AmpFlex
®
and
MiniFlex
®
deliver
output voltages
proportional to the frequency. A high current at a
high frequency can saturate the current inputs of the devices.
To avoid saturation, the following condition must be satisfied:
n=∞
n=1
[n. I
n
] < I
nom
∑
Where I
nom
is the range
of the current sensor
n is the order of the harmonic
I
n
is the current of the harmonic of order n
For example, the input current range of a dimmer must not exceed one fifth of the current range selected on the device.
This requirement does not take into account the limitation of the pass band of the device, which may lead to other errors.
