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 10th 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 events detection including waveforms recording,
