SMY 133 Analyzer

Multi-functional 3 phase digital panel meter, color display, embedded precise energy meter, 512 Mb flash memory, 96x96 mm

SMY 133 is a power anaylser with large bright graphical display. Instrument is designed for submetering and control in single- and three-phase low, medium and high voltage networks. It monitors all common parameters: frequency, line and phase voltages, currents, unbalances, active and reactive powers, power factors and up to 50 harmonics as well as the total harmonic distortion. It can optionally monitor power quality (PQ-S, interharmonics, flicker, voltage events, oscillographic records) and the ripple control signals (HDO, RCS).

Optional relay or SSR outputs can be programmed to control other equipment based on measured values (usefull for fan control, overvoltage/overcurrent pq relaying etc). Impulse outputs can also forward metered values as an S0 output. USB port provides quick, easy and reliable means for configuration and data acquisition. Optional serial or Ethernet interface allows it to be remotely managed via the ENVIS application. In combination with ENVIS.Online service its actual values can be also periodically downloaded and stored to the SQL database for further processing.

Data Acquisition and Processing

SML 133 instruments can optionally be equipped with a remote communication port (RS485, RS232 or Ethernet). As such it can be connected to any SCADA software with Modbus TCP or Modbus RTU protocol support. ENVIS software is supported and can be used to configure the instrument, to read out actual data from connected instruments. It stores them in archive or database and creates reports and analysis.

SMY 133 - Ordering information

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. 

Typical installation of ENVIS

 

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.
  • See: other built-in meters and analysers, portable analysers and data loggers, ENVIS 1.1 for data analysis.
