Sonel PQM 711 Power Quality Analyser

Class A IP65 Three Phase Power Quality Analyser with Fast Transient Capture for Pole Mount or other Rugged Applications. WiFi Communications


• Remote control and data transfer through a built-in GSM modem.
• Anti-theft feature – SMS notification in the event of position change (built-in GPS receiver).
• Real-time clock synchronized to GPS protocol.
• Remote control of the analyzer via software: Sonel Analysis (Wi-Fi and GSM for Windows) or Sonel Analysis Mobile
(Wi-Fi for Android).

Measured Parameters:

• Transients up to ±8000 V with max. sampling frequency 10 MHz. Minimal transient time is 650 ns 
• 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.
• Measurement of control signals up to 3000 Hz.
• 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, cosφ, tanφ.
• K factor (transformer overload caused by the harmonics).
• Up to 50th harmonics for voltage and current.
• Interharmonics measured as groups.
• Total Harmonic Distortion (THD) for voltage and current.
• Short-term (PST) and long-term (PLT) flicker (IEC 61000-4-15 class A).
