MEDCAL NT three phase network analyzer

MEDCAL NT is an advanced power quality monitor, specifically designed for Power Quality studies. It is extremely easy to configure and set-up, with no external switches or settings.

Covering the requirements of EN-50160, it is the first three phase network analyzer able to fully implement the recommendations of EN-50160 standard for fast voltage variations.

As an additional advantage, the RMS voltage profile can be stored whenever there is a RMS-related event: dip, voltage peak or fast voltage variation.

MEDCAL NT three phase network analyzer also includes an advanced transient detection capability on the voltage channels. A high-resolution voltage waveform will be recorded whenever there is a voltage distortion on the instantaneous voltage.

MEDCAL NT can store, under normal conditions, more than three months of recordings without external intervention. The absence of any mechanical elements makes the instrument extremely robust and reliable.

The included USB interface and cable allows direct communication with a personal computer. It is possible to connect a standard modem in order to operate a remote MEDCAL NT.

The instrument is designed for both laboratory and permanent installation, and is provided with both front (4-mm banana) and rear (screw-type) connectors.

Wall-fixing accessories are also supplied.

As an option, it is possible to include an internal GSM/GPRS modem for remote operation of the instrument.

With every MEDCAL NT, a copy of MEDCALScope PC software is included at no additional cost. MEDCALScope allows a complete and exhaustive analysis of recorded data. It is possible to save the recorded data for later use, and export the data to other computer applications, as well as check compliance with power quality standard.
