Description

ANALYZER MEASURES AND RECORDS ACCORDING TO THE IEC 61000-4-30 CLASS S STANDARD.

Features:

  • power to the analyzer is supplied from tested mains (internal power supply) and is used in all types of networks from 64 V to 760 V, with particular emphasis on measurements at low voltage poles, due to the ease of connection,
  • has an independent power supply socket, especially suited for voltage measurements for transformers and DC circuits,
  • built-in real-time clock.

Possible measurements:

  • Measurements according to EN 50160,
  • Voltage L1, L2, L3,
    – average, minimum, maximum and instantaneous values, range to 760 V, ability to work with voltage transformers,
  • Current L1, L2, L3, N (four inputs),
    – average, minimum, maximum and instantaneous values, measurement current with range to 3 kA (depends on used clamp), ability to work with current transformers,
  • Crest factor for voltage and current,
  • Frequency from 40 Hz to 70 Hz ,
  • Active, reactive, distortion, apparent power, including the type of reactive power (capacitive, inductive),
  • Power recording:
    – Budeanu method,
    – IEEE 1459,
  • Active, reactive, apparent energy,
  • Power factor, cosφ, tgφ,
  • Up to 40th harmonics for voltage and current,
  • Total Harmonic Distortion (THD) for voltage and current,
  • Short-term (PST) and long-term (PLT) flicker,
  • Unbalance of voltage and current,
  • Current and voltage events registration including waveforms and RMS graphs half period.
