PQM-702 Power quality analyzer

PQM-702 is a high-tech device providing its users with a comprehensive features for measuring, analysing and recording parameters of 50/60 Hz power networks and power quality in accordance with the European Standard EN 50160.

Manufactory: SONEL S.A. (Poland).

Description

Measured parameters
  • Voltages L1, L2, L3, N, PE (five measurement inputs) – average, minimum, maximum and instant values within the range up to 1000 V, interoperability with voltage transducers.
  • Currents L1, L2, L3, N (four measurement inputs) – average, minimum, maximum and instant values, current measurement within the range up to 6 kA (depending on applied current clamp), interoperability with current transducers.
  • Crest factors for current (CFI) and voltage (CFU).
  • Frequency within the range of 40 Hz – 70 Hz.
  • Active power (P), reactive power (Q), distortion power (D), apparent power (S) with identification of the nature of reactive power (capacitive, inductive).
  • Calculation of reactive power using the Budeanu method and IEEE 1459 method.
  • Active energy (EP), reactive energy (EQ), apparent energy (ES).
  • Power factor (PF), cosφ, tanφ.
  • K factor (transformer overload caused by the harmonics).
  • Harmonics up to the 50th in voltage and current.
  • Interharmonics measured as groups.
  • Total harmonic distortion THD for current and voltage.
  • Short-term (PST) and long-term (PLT) light flicker index.
  • Unbalance of voltages (in compliance with IEC 61000-4-30 class A) and currents.
  • Event logging along with oscillograms.
Features
  • Power from the measured network
  • Designed for use in virtually all network types from 64 V to 760 V directly, with particular emphasis on measurements at low voltage poles, due to the ease of installation
  • Independent power supply makes it particularly suitable for measurements behind voltage transformers. It can also be used for measurements in DC voltage systems
  • Remote configuration and data transfer in real time using the built-in GSM modem
  • Anti-theft function – text message notification in case of position change – built-in GPS receiver
  • Real time clock synchronized using GPS protocol
