    What does the PQube 3 record? In a few words, your PQube 3 detects and records disturbances on the mains circuit: Sags/dips, swells, interruptions, frequency variations, HF impulses, Rapid voltage changes, waveform changes and more… It also records steady state power quality parameters like flicker, unbalance, THD harmonics and Interharmonics.

  • Page 6: What Software Do You Need

    PQube 3 supports PT ratios (up to 50000:1) and CT ratios. Beyond AC voltage, your PQube 3 can be used to monitor DC voltage at up to 60 Vdc, or up to 1200 Vdc with an optional interface module (ATT1). For both DC voltage and DC current use the ATT2 interface module.

  • Page 28: Installing Split Core Current Transformers (Cts)

    Note: You can skip this chapter if you are installing PQube 3v or PQube 3vr (voltage analyzers) Your PQube 3 records AC current by measuring the secondary circuit of a current transformer (CT). When installing current transformers, it is important to match the phases to the voltage inputs and current input (connect the L1 voltage input and the L1 current sensor to the same conductor).
  • Page 29 POWERSIDE Ultra-Precise CTs are UL listed and utilize a 0.333V secondary output to match your PQube 3’s current input terminals. A burden resistor is built into the CT so you do not need to worry about hazardous open circuit voltages.
  • Page 30 Your PQube 3 comes standard with 8 current input channels, which are typically used to measure L1, L2, L3, N, E, plus 3 additional single-phase channels. The current channels on your PQube 3 are rated for 0.333V nominal inputs, and they are designed to be used with CTs with 0.333V secondary.
  • Page 31 The CTI module inputs are installed in series with your 1 A or 5 A secondary circuit. The terminal block on your CTI module is connected to the 0.333 V current input channels on your PQube 3. Each CTI module includes 4 current channels, so you can use up to 2 CTI modules per PQube 3.

  • Page 43 The first step of the verification is to make sure that the main LED of the PQube 3 blinks in GREEN. Your PQube 3 will not begin recording until it has locked onto the power configuration. The minimum lock-on voltage is 30 Vac applied between L1 and N, or between L1 and L2.

  • Page 44: Troubleshooting: Common Installation Errors

    It is important to correctly connect your CTs (or use the method above to correct a wiring error). Power (watt) calculations are made by multiplying the instantaneous current by the instantaneous voltage. If one or more of your current transformers is incorrectly set up, your PQube 3 will calculate negative power for that phase.
