Current Measurement

BDR01 Series Shunt

The BDR01 series shunt provides an accurate current sensing solution for current transducers/transformers outputting a current signal, the shunts feature BNC input and Output connectors.

The BDR01 is ideal for use in conjunction with current output transformers or zero flux based current sensing transducers such as the LEM IT and ITN series. The BDR01 extends the low current sensitivity significantly due to the higher shunt impedance, this is essential for current transducers with high “turns ratios”.

While the BDR series was primarily designed for use with the PPA series power analyzers from N4L that provide exceptional wideband accuracy, dynamic range and common mode rejection, they can also be used as a precise current sensing device for other equipment.

TT-HV-250 High Voltage Probe (2.5kVpk)

Although N4Lpower analyzers feature 3000Vpk (PPA4500 and PPA5500) and 2500Vpk (PPA500 and PPA1500) voltage inputs, a particularly useful feature of all N4L power analyzers is the 3Vpk BNC inputs situated on both the voltage and current channels. This results in the ability to measure 6 x high voltage signals (with attenuators on external inputs) on a 3 Phase instrument, in this case the three current channel “External Inputs” could be used to measure a voltage via an input attenuator such as the TT-HV250.

PCIS Phase Controlled Inrush Switch

The Phase Controlled Inrush Switch provides the engineer with the ability to “program” the phase angle of the input power waveform at which power is applied to any DUT. The PCIS allows the user to pre program 0º, 45º, 90º, 135º, 180º, 225º, 270º and 315º. This function is particularly useful when testing the inrush current of a device which is either inductive or capacitive, allowing “worst case” phase angles to be applied to the device under test. The PCIS is only suitable for use with a supply frequency of 50-60Hz. Use with higher frequencies may damage the unit.
