Relay Coordination and Arc Flash for Saudi ARAMCO
The objective of this study is to verify and validate the over current settings applied in the existing electrical power systems at substations for the safety of personnel and equipment at rastanura south and north terminals detailed scope of this relay co-ordination study is to update the applied settings in to etap model, generate toy curves, verify and validate the settings applied. the purpose of the arc flash study is to fix, verify, define and validate the personnel safety reguirements along with equipment protection requirements.
OGDCL Relay Coordination Studies
The existing electrical protection system of the Dakhni Gas Plant has performed its function more than 25 years During the up-gradation of Ruston Gas Turbines new control and protection system was installed which is more advance and responds more quickly/accurately in sensing the faults than the already installed electro-mechanical protection relays. Scope of the study:
Offering Power System Solutions tailored to fit the needs of:
