Electrical Measuring Instruments
Synchronization Meter SQ0214
If you are looking for manually or semi-automatically synchronise generators and bus bars, you have come to the right place. Our synchronization meters are truly unique products. They measure phase differences between generator and bus bar, voltages and the frequencies of the two systems.
They can replace up to five instruments, occupying less space and giving you more information, for a lower price. Furthermore, they are equipped with status output, they are also appropriate for mounting on ships. They are equipped with LED diodes, so you can actually see the phase difference. When synchronising conditions are set, the synchronizing relay is activated.
If you are interested in the phase difference between generator and bus bar, select SQ 0204. If you also want to have information about voltages and frequencies of the systems, select SQ 0214.
The SQ 0201 phase sequence indicator is intended for determining phase sequences in a three-phase network, from 200 V to 500 V and from 50 Hz to 60 Hz. The indicator is provided with two built-in glow lamps indicating L1, L2, L3 phase sequence.
Features of SQ0214
- Five instruments in one
- Circular display of Δ phase difference
- Magnified display of phase difference Δ = ± 20°
- Microprocessor processing
- Simple synchronisation conditions setting
- Output relay for synchronisation (pulse or continuous)
- “Dead-busbar” functionality
- Power supply from bus bar or generator
- Standard 96 x 96 mm DIN casing
- LCD with backlight for display of busbar & generator voltage, frequency and Δ
- Flash memory
- High immunity to EMC disturbances
- Status output (ship version)
- Green LED for indication of both voltages
- LED indication for synchronisation output
Measuring Transducers iMT540
The new series of measuring transducers iMT540 are intended for measuring and monitoring single-phase or three-phase electrical power network.
They measure TRMS value by means of fast sampling of voltage and current signals, which makes instruments suitable for acquisition of transient events. A built-in microcontroller calculates measurands (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from the measured signals.
Features of Measuring Transducers iMT540
- Voltage and current auto range measurements up to 600 V, 12.5 A.
- Wide measurement frequency range 16 Hz - 400 Hz.
- Power accuracy class 0.2 (IEC-688), 0.1 on communication.
- Up to three communication ports.
- Remote display iRD500.
- Up to four I/O modules.
- Powerful analogue output; 6 voltage and current ranges, non-linear characteristics.
Advanced Power Quality Analyzer iMC784
The iMC784 can be used in power utilities (for evaluation against standards) as well as for industry purposes (monitoring supplied power quality). It performs measurements in compliance with regulatory requested standard EN 61000-4-30 and evaluates recorded parameters for analysis according to parameters defined in European power quality standard EN50160.
Power Quality Analyzer iMC784 is a perfect solution for permanent Power quality monitoring.
Class A certified PQ meter is intended for permanent power quality monitoring and detailed event analysis on all voltage levels
Its advanced operation is useful for network specialists to help finding problems in a network, forecast potential problems and for future network planning
Up-to-date communication support and standard data formats enable fast integration into network or industry management systems
In EU countries it is mandatory for utility companies to regularly report about Power Quality. Industry is also highly dependent on good Power Quality and therefore also interested in such monitoring. For that reason power quality monitoring has been standardized. Proper methods are defined with IEC 61000-4-30 ed.3 standard and sub-standards for harmonic analysis and flickers.

- High accuracy (0.1%) as required within EN61000-4-30 Ed. 3 Class A
- User friendly setting and analysis software MiQen
- Waveform and transient recorder with programmable sampling time (%mygt% 600 samples / period), pre-trigger and post-trigger time
- Internal memory (up to 8GB) for recording all measured parameters, disturbances, waveforms, alarms, PQ reports and time-stamped
- Details about anomalies.
- Automatic measuring range up to 1000 VRMS, 12.5 A direct connection
- Measurement of 4 Voltages and 4 Currents with 32 kHz sampling time
- Serial, USB and Ethernet communication with support for MODBUS, DNP3 and IEC61850 (optional) protocol.
- Up to 20 Input and Output modules for control purposes and monitoring of other physical parameters (temp., wind speed, pressure…)
- Standardized PQDIF and COMTRADE format support for storing recorder data
- Comprehensive 0.2S energy measurement feature (4 quadrant energy measurement, 8 counters, up to 4 tariffs, tariff clock, pulse outputs...)
