The particular optimized alternative to decrease switching over-voltages.
POINT-ON-THE-WAVE CONTROLLERS supply built in advantages to restrict the particular over-voltages triggered by switching operatiors under unparalleled valuations

The particular Alstom Grid RPH3 can certainly switch the troublesome pre-insertion resistors connected with the circuit-breakers for that current uses of transmission cables energisation as well as reclosing, shunt-capacitor over shunt reactor changing, energy transformer energization.
Additionally, RPH3 contains revolutionary particular characteristics to help lessen the switching tensions regarding transmission circuits linked to shunt compensation units.

Usage aspects
The particular RPH3 is actually highly suitable for:

Switching over HV on EHV transmission collections using quick compensation ( 3-stage as well as individual-stage auto-reclosure), discerning the particular conditions of use of shunt compensation
Energization of huge energy transformers (inrush current and remanent flux)
Switching regarding shunt response as well as capacitor banks RPH3 rewards implementation assists returning to the particular switching safety ranges regarding the transmission boards as well as the tools from the S/S
