DEIF MVR-210 series Medium Voltage Relay

General description

The MVR-200 series provides optimal performance for medium-

and high-voltage protection, control, measurement, and

monitoring of applications.

The MVR is designed for use as stand-alone protection and

measuring unit or as a component in larger applications,

connected through IEC 61850 GOOSE messages in three-phase

electrical power networks that require marine approval.

The MVR wide frequency tracking algorithm ensures stable

measurement and protection from 6 to 75 Hz, where variable

frequency is present, such as marine applications and generators

running in island mode.

The MVR measures and calculates values for AC voltage, AC

current, active/reactive power, power factor, frequency, THD and

harmonics (up to 31st). All values can be seen on the display.

A 5 ms scan time ensures that faults are quickly registered.

A 64 samples/cycle fault record function measures data for up to

100 faults for 10 seconds each. This function can be configured

to create records before the error, making it easier to understand

the causes of the error and prevent it from re-occurring.
