MI 2892 Power Master is an ideal instrument for long term recording as well as for onsite troubleshooting and finding of hidden power quality problems such as:

  • Voltage Dips and swells;
  • Harmonic Distortion;
  • Voltage Unbalance;
  • Flicker;
  • Transients;
  • Inrush current recording.

Due to the Instruments large Memory facility, Power Master is suitible for long term recording and optimization of load and energy profile.

Optional GPS enables the user to observe disturbance spreading over the network and estimate impact under various conditions.

PC SW PowerView enables automatic generation of professional reports for voltage quallity evaluation in accordance to EN50160.

Recorders configuration of the MI 2892 Power Master is one of the simplest ever made. Even non skilled user can easily capture all needed parameters, for torough analaysis.

The MI 2892 Power Master has been designed with leading Industry Experts to provide a simple menu configuration. In the past the built-in technology of the power quality analyzers didn't enable the possibility to record large amounts of parameters. Therefore the engineers often had problems to set the recorder correctly. Metrel's engineering team has decided to make a market defying product with a clear and easy to use Menu Structure, meaning the engineer on site has complete control and peace of mind that the MI 2892 will record all of the data being requested In the General recorder, the user selects the time interval, which will also include Voltage events, and also include any alarm triggering points. The MI 2892 Power Master will automatically record over 4000 different parameters.

To make the instrument even more powerful Metrel implemented option of simultaneous recording with GENERAL and WAVEFORM RECORDER. This feature enables the user to capture inrush currents, anomalies on voltage and current plus several other trigger options while general recorder is active.

PowerMaster enables Transient recording with sampling frequency >50kHz. Trigger can be set to envelope or level mode. In continuous mode the instrument can record up to 200 transients.

MI 2892 Power Master's measurements menu is specially designed for onsite troubleshooting. With navigation keys user can simply toggle between several intuitive menus to discover hidden power quality problems onsite.

Several different options are available for each troubleshooting tool. Simply by using the Function keys the user can select between the different variants for each option.

Vide range of different current clamps are suported depending on aplication.

Quick set keys located beneath the function keys enabling user to reach the most important tools simply by pressing them.

PowerView software is a powerful platform for downloading, analysing recorded data and creation of power qualty test reports. PC Software contains a package of functionalities needed for profound evaluation of power quality
phenomena, data comparison and creation of complex test reports. It works in conjunction with Metrel new generation power quality analysers. For the instruments equipped with GPRS functionality PowerView enables
remote control of the instrument as well.

The best way to guarantee that process equipment is compatible with its electrical environment is to require the equipment to comply with voltage sag standards ITIC and CBEMA curves are representing the limits for safe operability of IT equipment.

Depending on selected record type, different views are available (Record Information view, Trend Chart view, Table view, Waveform Scope view, Voltage Quality view, etc.)

Automatic voltage quality analysis in compliance with custom or predefined EN 50160 Power Quality criteria and quick report printing.

When instrument is connected with PC, real-time observing of signals and parameters is possible via PowerView while instrument is measuring / recording in the background.
