VM257.EN002

For the I

and U

measurement, the fundamental frequency

components are used. Thus, the degree of the third harmonic
attenuation is at least 60 dB, which contributes to the

extremely high accuracy of the earth fault protection.
The directional earth fault protection measures the residual
voltage U

, earth fault current I

and the phase angle

between U

and I

The directional earth fault protection includes two separate
protection stages, that is, I

> and I

>>. Both the stages have

their own operation time settings. The protection stage starts
when the setting values of I

> and U

> are simultaneously

exceeded.
The I

0Res

mode (I

0cos

) is used in rigidly, resistance and resonant

earthed networks, and in the I

0Cap

mode (I

0sin

) in isolated

networks. The user can set this characteristic, or it can be

controlled dynamically using any digital input. The control

input is usually used in compensated applications, where the
compensation coil can be switched on and off.
