1.5.3 Measure currents from secondary of current transformers (CTI-
1A/CTI-5A)
Your PQube 3 comes standard with 8 current
channels which are compatible with CTs with
0.333V secondary.
But if you need to measure CTs with 1A or 5A
secondary wires for your application, use the CTI
Current Transformer Input module.
There are two versions: one with 1A input and
one with 5A input. Use the CTI module that
matches the secondary rating of your external
CTs.
There are four current inputs per module. Your
PQube 3 can accommodate up to two CTI
modules.
Use this module if your application requires
ANSI C12.20 Class 0.2 or IEC 62052-22 Class 0.2S
revenue grade accuracy.
1.5.4 VAT2-600 Three Phase AC/Dual DC Voltage Attenuator
The perfect solution for monitoring two sets of three-phase AC voltages
such as the primary and secondary side of transformers or the input and
output of a three—phase UPS.
