VHR network analyser equipment
These devices measure instantaneous physical values of electricity generating and consuming devices and of the electricity transfer and distribution network. High precision measurements are taken throughout a given period. Instantaneous or averaged results can be stored to be used by other systems or for further processing and evaluation.

- Common utility software for all types
- Vandal-proof for outdoors and tabletop versions available
The VHR family of devices is so called “network analysers” used for quality control in electrical grids, measuring and evaluating the quality of the received electricity in accordance with the EN 50160 standard.
VERTESZ is undertaking prepaid measurement sessions as well. Please inquire at our regional sales representative!

Utility software solutions:
Vhr consol – Readout and parametrisation software for VHR devices. It is capable of programming any VHR device. Programming consists of setting the information required for the report: type of measurement instrument, nominal value of current and voltage, the ratio of the current and voltage transformer, location and duration of the measurement, the name of the user, averaging time, etc. Readout of the result is via Vhr consol as well.
Reginfo –automatic measurement controller and integrated evaluation software. It is absolutely essential when using several VHR devices. The software makes instrument maintenance easier, programming them quicker, and it can also automatise processing and evaluating measurement results based on user-defined criteria.
FA phase identifier (pair of devices)
165x82x30mm
(without antenna and cable)
IP40 ■ 0…+50 C°
Application:
The pair of FA-TX and FA-RX devices can be used to take measurement at various supply and consumption points of the given segment of a network …
- Establishing relative phase order
- Determining the angular position between phases
- Identifying phases compared to the reference poin
- Identifying the zero current wire
- Determining GPS coordinates
Power supply:
FA-RX: 9V DC (battery)
FA-TX: 70-265V AC
Range:
1000…2500m
depending on the geographic location and the type of antennae used
For identifying phases at supply and consumption points, compared to the reference junction.
The device uses the open RF band at 868 MHz frequency to communicate via radio. This frequency is available for use. The result of the measurements are displayed by LEDs and an LCD display.
