<f and >f in P243

Hi Experts,

I need to know about activating under/over frequency protection setting in Micom P243 relay used for protection of MV motors.

I have checked group 1 settings and there is no such protection found in protection functions. I have downloaded PSL file as well but unfortunately I don't understand it. Can someone here guide me about it?

Thanks,

Hello,

Over frequency protection is not implemented in Micom P243.

Under frequency can be activated. To display the settings in Group 1 menu, Under Frequency must be first Enabled in the CONFIGURATION menu.
