VIP 400/410

VIP 400 are self-powered protection relays requiring no auxiliary power supply for the main protection functions. Self-powered protection relays increase the availability of the MV network and are suited to most applications.

Designed to respond to voltage drop.
Not dependent on UPS systems.
Less dependent on the external environment (EMC, LV overvoltages) because they require no external connections.

VIP 400 protection relay suits to the buildings and MV/LV substation utilities. It provides protection curve to help protect against overloads, short-circuits and earth faults with DT (Definite Time) and IDMT standardized tripping curves and thermal overload protection. The functions are completed with measurement of currents, multi-language display and a complete set of metering.

VIP 410 protection relay suits to building substations, and MV/LV substation utilities and for power system MV loops with automation. It includes a dual power supply (self-powered plus auxiliary power supply) for communication with remote communication with Distribution Management System (DMS) and Remote Terminal Units (RTU), remote control and alarming, time stamped events recorded, load history, over-current and breaking profile. It provides same protection functions as VIP 400 and additionally it can detect cold load pick up. It also allows remote configuration with setting groups selectable according to the configuration of the MV loop.

VIP Parameter and Protection Settings

All VIP parameters and protection settings should be established in advance by the design department responsible for the application and should receive customer approval. It is assumed that the study has been conducted with careful attention, and potentially reinforced by a discrimination study. All VIP parameters and protection settings should be ready for commissioning. The VIP settings sheet can be utilized to document all the parameters and protection settings that need to be entered.

Presentation

The User-Machine Interface (UMI) on the front panel of VIP relays consists of a display, LEDs and keys. A sealable pivoting flap helps to prevent access to the setting keys by unauthorized persons.
