Power Grid & Substation Automation
VOOHU LAN transformers, SFP optical ports, current transformers, isolated power magnetics and protection devices serve every class of power grid terminal, from the station-level network down to transformer-area data acquisition. The architecture below runs from dispatch, distribution automation and metering master stations, through substation automation equipment such as protection relays, measurement and control units, merging units and intelligent terminals on IEC 61850 station and process bus networks, to distribution, feeder and transformer terminal units (DTU / FTU / TTU), concentrators and smart meters, and on to distributed PV, energy storage and EV charger connections.

Component-level reference designs
Component-level illustrative reference designs compiled by VOOHU FAEs for typical devices. Each illustrative board marks every component position, its function and the VOOHU part numbers available, so you can review selection notes and packages position by position.
