3-phase voltmeters
EP27, EP29
Voltmeters equipped with a change-over switch EP27 and EP29 type are destined to measure phase-to-phase and line-to-line voltages in low voltage power networks.
A switch installed on the left side of the dial enables the selection of the measured voltage. They are particularly useful for measurements in electrical machine safeguard systems.
