Function 50 and 50P
Function 50 and 50P
(OP)
Hi!
¿Does anyone know the diference between the protection functions 50 and 50P. The same thing with 51 and 51P.?
Im not taking about 50/51N
In some projects I saw that engineers make diference between 50 and 50P
Thanks in advance
Martin

Usually menas the same, but protection engineers make diference between 50 and 50P. That way my question

In few newer relays used also 50P-1, 50P-2.
Actually it's DT overcurrent function.

Get the person who mentioned the numbers to clarify the application - asking others to interpret what another person intended is normally the cause of the mistake/argument.
