An A321 aircraft had an MEL for a disconnected IDG that was applied in November 2013. About an hour into flight; while doing standard ECAM check; we noticed that the IDG on the Electric Page was pulsing due to a High Temp 140 C and climbing. [We] contacted Maintenance Control thru Dispatch; using onboard phone. Was instructed to disconnect IDG again and the temperature started to drop after peaking at 155 C. Somehow the IDG got reconnected in ZZZ
Flight crew was instructed to accomplish another disconnect of an Integrated Drive Generator (IDG) on their A321 aircraft after they noticed the IDG on the ECAM Electrical Page was pulsing. The IDG had previously been deferred and considered disconnected.
