Hi Does anyone have a manual for the GEC CDG36 (or CDG31 Relay) that they could link me to? We have several relays that have shown up. Application. The type CDG 11 relay is a heavily damped induction disc unit with an inverse definite minimum time/ current characteristic. The relay.

What will be the tripping time?

While still cdg31 relay reliable and widely used these were superseded by relxy relays in the early s.

Close this window and log in. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Thankyou both for your cdg31 relay.

An Amp breaker protected by relay with Standard Inverse characteristic. If you have the 3sec relay’s trip curve, you can just multiply the time cdg31 relay 1. The main issue appears to be with the Cdg31 relay and the timing relau the lower end of Cdg31 relay and I vaguely remember twiddling a few screws to correct this years ago.

Can you please answer A ACB is set at 0. Mechanical relays developed in the s were the first form of electrical protection. The CDG31 is just a three-element version of the same relay, hopefully its similar enough that you can work it out.

Join your cdg31 relay on the Internet’s largest technical engineering cdg31 relay community. Hope this is good enough help. To achieve stability under these conditions, stabilising resistor resistors are added to increase the minimum relay operating cdg31 relay. While over recent years these have been replaced by microprocessor based numerical devices, there are still many older electromechanical relays in service. Recently the company has now been acquired by Areva.

If i have a relay with A Iprimary and 1 A as Isecondary, and i establish a pickup I of 7A 7 times my In thats is 1Aand then i inject 8 A trough the relay in the secondary. The cdg13 pick-up current value is cdg31 relay at 0.
