Mb control & systems provides the latest in power quality monitoring, model ezpac disturbance-cum-fault recorders and analysers. Provide many unique features are provided by these disturbance recorders for monitoring power quality, harmonics, disturbances, faults, sequence of events and measurement of all the electrical parameters. Following are some of the technical features of these recorders and analysers which include: have up to 132 mb nvram to store all the parameters, waveforms and events; accuracy of measurement is 0.2s as per iec687; sampling rate is 128 samples per cycle for each phase voltage and current. As per ieee1159 and en50160, power quality recording is done. Dataa logging and oscillographic recording is done for impulse, undervoltage, overvoltage, interrupts, sag, overvoltage, swell, frequency variation, transients, voltage imbalance, negative sequence currents and voltage, harmonics and interharmonics. Harmonics data is available up to 63rd harmonics with direction. Advanced waveform and data analysis software pas is supplied along with the ezpac. Sequence of events is recorded with 1 msec time stamping. Provides various types of communication ports are provided by the ezpac. Three rs485 ports, usb port, ethernet tcp/ip interface, direct modem interface, irig-b interface and many more. The ezpac is best suited for recording and analysis of disturbances, faults and pq in all types of electrical substations, feeders, etc.
