SMP and SMPQ

Power-voltage quality analyser for panel - combines accurate 3-phase energy 4Q, 3 tariff TOU meter - power measurement device - provides data logging, power quality analysis -  advanced alarms and programmable input/output capabilities

Compact power quality analyser SMP and SMPQ are a class S power monitoring devices according to the IEC 61000-4-30, ed. 2. SMPQ also evaluates and archives power quality and distrubance data according to EN 50160 standard. An important part of this compact platform is an embedded four quadrant electricity meter with automated meter reading archive (load profiles). Functionally they are identical to SMV and SMVQ analysers, the only difference is the provided type of display. 

These instruments offer a wide variety of programmable input-output and communication options. By default every device has an USB connector. Optional RS232, RS485 and Ethernet can be ordered. In more complex application where interactions with other devices is desirable the outputs can be programmed to relay or pulse outputs of various quantities. A temperature or another analog quantity can be measured from its analog input.

    Optional Accessories

    X/5A: standard measuring current transformers with IN=5A resp. 1A

    CT with secondary nominal current 5A resp. 1AInstrument in this oprtion can be connected and configured to measure currents with any 1A/5A CT the customer might already have installed. This type of standard CT with 1A or 5A output is most common and supported with the regular type of instruments (default option). We also offer various split core measuring CTs with 5A secondary output as an optional accessories to our instruments. These are suitable for simple online installation of the measuring instruments and usually do not require disasembling of the measured appliance.

    Sxxx/Pxxx: CT Assortment for high ratio CT option of instruments

    Wire through CT with small nominal output current.This option of analyser is shipped with split core extrenal CTs (option Sxxx) or wire through external CTs (option Pxxx). These CTs have high transforming ratio and the secondary current is relatively low. Its biggest advantage is simpler instalation and handling when compared to the standard X/5A CTs. It can be used to measure directly currents of nominal value up to 600 AAC. Specific CTs are calibrated and ordered with each instrument.

    Bxxx Flexible Current Sensor (Rogowski CT)

    A3000 Flexible current sensor Bxxxx (Rogowski coil) is dedicated to measure broad range of AC currents in LV networks. These sensors are typically intended to be used with our portable instruments. Each sensor is equipped with an amplifier box and a range control switch. Nominal measured current is optional - 10 000, 3 000, 1000, 300 or 100 AAC.

    The B3000, B1000 and other Bxxx flexible current probes work with: power quality analyser SMV & SMVQ (option F), SMP & SMPQ (option F), compact portable SMP-BX and SMPQ-BX analysers and SMP-CA portable analyser and data logger.

    Ordering codes for B3000 and B1000 CTs.

    ENVIS application suite provides all features for basic instrument management (configuration, supervision, fw update). It also downloads and archives data from all the supported instruments. import/export, data analysis and advanced reporting of the records is also provided. ENVIS is available free of charge to be used with all our instruments.

    Typická instalace aplikace ENVIS

    ENVIS.Online system service can be used to implement complex power quality monitoring and/or energy efficienci control and monitoring systems. By using email,  SMS or SNMP all registered users and administrators can be warned upon exeptional situations, malfunction of supply or monitored instruments or it can be used to post periodical analysis/reports.

    Additional plugin modules can also add special features or customizations to booth ENVIS and ENVIS.Online in a modular manner.

    Optional firmware modules

    Voltage and power event cycle data logger module.
  • Ripple Control (Mains) Signals - RCS Module: for measurement, recording and analysis of a ripple control signal. Several formats of the telegram are also supported for decoding.
  • Voltage Events - VE Module: for recording and evaluation of voltage events (SMVQ & SMPQ does include this feature in its default configuration).
  • General Oscillograms - GO module: for detection and precise recording of various waveform distortions. This module records the so called oscillograms of voltages and currents in extended detail, capacity and trigger options into the flash memory.
  • Modbus Master - MM module: in supported instruments with memory it activates new option to record Modbus data from connected slave devices. It can work as a datalogger to NOVAR PFCs as well as to local sub-meters or other Modbus sensors.
