Voltage Measurement

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

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
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.
