What Are Over And Under Current Relays? |
|
Answer» Overcurrent relays are those that operate when the CURRENT in a line exceeds a predetermined VALUE. (eg: INDUCTION TYPE non-directional/directional overcurrent relay, differential overcurrent relay)whereas undercurrent relays are those which operate whenever the current in a circuit/line drops below a predetermined value.(eg: differential over-voltage relay) Overcurrent relays are those that operate when the current in a line exceeds a predetermined value.
