Lovato PMVF30 interface protection system compliant with CEI 0-16 for medium-voltage generation installations, featuring dual-threshold minimum and maximum voltage and frequency protection.
£3,954.64
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.
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.

The PMVF30 monitors voltage and frequency at the connection between a local electricity generation system and a medium-voltage distribution network, controlling the interface device when abnormal conditions are detected.
The Lovato PMVF30 is compliant with the Italian CEI 0-16 standard for interface protection in medium-voltage systems.
Medium-voltage measurements are normally obtained through external voltage transformers. The PMVF30 can also measure compatible low-voltage systems directly.
The unit supports external current transformers with either 1 A or 5 A secondary outputs.
Yes. Optional expansion modules are available for RS485, Ethernet, USB and RS232 communication, allowing integration with external monitoring and control systems.
Lovato PMVF interface protection systems are used by electrical engineers, renewable energy specialists and panel builders to provide dependable grid supervision and disconnection control for medium-voltage generation installations.
