MiCOM P122 Question

[ElecEng81]

Hi,

I have a quick question regarding the MiCOM P122.

In the relay manual it states that the operation TIME tolerance for thresholds I>, I>> and I>>> is +/- 2% +30...50ms. Therefore, am I correct in thinking the NEGATIVE tolerance for a set curve is 2% of a set value. Also, that the POSITIVE tolerance for a set curve is 2% of the set value PLUS 50ms.

Many thanks in advance.

Can you post the manual?
