I want to know the basics of ESD SYSTEMS. As I'm working in oil & gas as an plant operator, and I've seen our Instrument crew work on ESDsystem and override switches during their maintenance job. So I'm very much interested in learning about this.
Please provide me some explanation or links which can help me study!
Typically there are 2 systems inside plant as follows:
- DCS for controlling & monitoring the plant
- ESD/SIS for Safety System (Plant Shutdown)
These 2 (two) system running independently.
Perhaps, your Instrument crew override/bypass switches to avoid Plant Trip.
There are a lot of article in internet that could used.
