AEMC offers three-phase power quality analyzer

October 24, 2014. CAS DataLoggers and AEMC have introduced the new PowerPad III Model 8333, an easy-to-use, compact and shock-resistant three-phase power quality analyzer. It enables technicians and engineers to measure and carry out diagnostics and power quality work on single- or three-phase networks. Three current and four voltage input terminals are provided, and the device is IEC 61000-4-30 Class B and safety-rated to 600 V CAT IV. 

The new Model 8333 has memory available for storing trend data, alarms, transients, and snapshot data. The data logger is capable of storing up to 12 screen snapshots, up to 51 captured transients that contain four cycles for each active input, and 4,000 alarm events from up to 10 different parameters. Users can record trend data for days, weeks or even months.

The data logger is part of a kit that includes three MN193 current probes, four black 10-ft voltage leads, four black alligator clips, twelve color-coded input ID markers, a NiMH battery, 110/240-V power adapter, USB stick, user manual, and free configuration software.

Applications include

  • verification of power distribution circuits,
  • troubleshooting of in-plant power distribution panels and individual machinery,
  • monitoring pad mount transformers and phase unbalances,
  • determining harmonic problems originating from source or load, and
  • determining transformer K-Factor.

The instrument measures TRMS voltages up to 1,000 V RMS AC/1,200VDC for single- or three-phase networks, and it measures TRMS currents up to 10 kA RMS (sensor-dependent). It records and displays trend data as fast as once per second for one month (up to 29 variables). It captures up to 51 transient occurrences on all voltage and current inputs. It also measures harmonics (referenced to the fundamental or RMS value) for voltage, current or power up to the 50th harmonic.
