VIP protection relays are self-powered while traditional relays require an auxiliary power supply.

Self-powered protection relays increase the availability of the MV smart grid and are perfectly suited to most applications.

Insensitive to voltage drop caused by faults
Not dependent on UPS systems (weak point of electrical installations)

Less dependent on the external environment (EMC, LV overvoltages) because they require no external connections.

Remote communication, making self healing and monitoring possible, with VIP410.

In addition, the VIP offers optimized performances due to integrated protection chain and low current activation.

VIP is a part of a complete and pre-tested protection system: specific High sensitivity sensors and Mitop actuator enable savings on space and cabling time.

VIP400: Self-powered protection relay

Energised by the CTs. It does not require an auxiliary power supply to operate protection
Phase and earth fault protection
Thermal overload protection
Load current and peak demand measurement functions

VIP410: Dual powered protection relay

Same self-powered functions as the VIP400 plus an AC or DC auxiliary supply to power certain additional functions that cannot be self-powered:

Sensitive earth fault protection
External tripping input
Cold load pick up
Communication (Modbus RS485 port)
Signaling relay
