Why Choose the Lovato PMVF30 Interface Protection System?
The Lovato PMVF30 is an advanced interface protection system unit developed for electricity generation installations connected to medium-voltage distribution networks. Compliant with the Italian CEI 0-16 standard, it continuously monitors voltage and frequency conditions and controls the interface device when electrical parameters move outside the permitted operating limits.
The PMVF30 provides dual-threshold minimum and maximum voltage protection together with dual-threshold minimum and maximum frequency monitoring. Measurements can be obtained through voltage transformers in medium-voltage systems or directly from compatible low-voltage circuits, making the unit suitable for a broad range of grid-connected generation applications.
With a clear graphical display, configurable protection functions, current-transformer inputs and communication expansion options, the PMVF30 provides dependable supervision for photovoltaic plants, cogeneration installations and other distributed energy systems. Its robust 96 × 96 mm flush-mounted housing and IP65-rated front make it suitable for professional control and protection panels.

Reliable Medium-Voltage Interface Protection
Generation systems operating in parallel with a public distribution network must be disconnected whenever voltage or frequency conditions exceed permitted limits. The Lovato PMVF30 continuously supervises these electrical parameters and operates the interface device to isolate the generation system when an abnormal grid condition is detected.
The unit can receive measurements from medium-voltage transformers or directly from low-voltage circuits, providing flexibility across different system designs. Its configurable protection thresholds, relay outputs and digital inputs support coordinated protection strategies for renewable energy plants and industrial generation installations.
Typical Applications
- Medium-voltage photovoltaic installations.
- Cogeneration and combined heat and power systems.
- Distributed electricity generation plants.
- Industrial generation systems connected to the grid.
- Wind and renewable energy installations.
- Grid interface protection panels.
- Parallel generator connections.
- Utility and energy monitoring systems.
