Transformer winding temperature trip. 2

Dear All.
Do you use for such trip some electronic devices, like to EPT202.

its good device, but I wouldn't like use it for trip of GSU, only as alarm or cooling control.
What is your practic?
Thanks in advance.

We used to specify a Temp Monitor unit from Qualitrol, but now we use the Schweitzer SEL-2414. We have outputs for both alarm and trip functions. So yes, we do trip the transformer on high winding and/or oil temp.

Thanks a lot David for information.

This is important part :
The SEL-2414 Transformer Monitor withstands harsh physical and electrical environments and is built and tested to meet mission-critical IEEE and IEC protective relay standards.
