RE: CDG 36 Relay CURVES
A CDG36 relay is a 3 pole relay with a standard inverse characteristic.
Please note a CDG36 does not include any high set elements.
If it did the model would be CDG66 (or CDG56 if hi-sets on the O/C only)
RE: CDG 36 Relay CURVES
Like DiscoP suggested, contact your local ALSTOM supplier, or search for ALSTOM on the internet. They've sent me a copy in pdf-format.
Also, see Thread279-13401 (The formulas for the different curves stay the same, it is just the case number that change.)
It would be good if you can find someone who can cut the different curves with perspex, to use with a 3log paper. A company in South-Africa cut mine, and it is very handy to use when you are in the field.
Good luck

CDG36 is the same characteristic as CDG31 (or CDG11) - ie Standard Inverse
The difference between the two relay types is the tripping circuits. CDG*1 has one contact on the disc, CDG*6 has 2 contacts.

Certainly a person could do it yourself. I've tried it first with glass (not very successful, sides very sharp, breaks easily etc.) then I tried perspex. The problem to do it yourself is to cut the curve, people with cutting machines cut the curves very easily (at minimal cost) But yes, you're right, you can do it yourself.
