Portable Three-Phase Voltamper Phase Meter VFM-3 for Electrical Network Analysis

Voltampere-phasometer VFM-3 is a portable device for measuring the parameters of three-phase networks with vector diagram output on a 4.3 inch colour TFT-display. The device is used in the adjustment of phase-sensitive relay protection schemes, in complex tests of protection of generators, transformers, lines, in the circuits of current and voltage transformers, and also serves as an indispensable device for checking the correct connection of electricity meters.
