643 busbar B90

leading the commissioning team to make the primary stability for busbar

And 2 transformers

• Leading the commissioning team for testing all the schemes .

Testing protection relays type pcs and micom (distance ,transformer differential , and busbar protections )

leading the team for commissioning activities such as testing GIS scheme primary stabilities

• Testing GE relays , siemens ,&Micom relays for many projects for example
• alshabab power plants extension one and half cb 2 feeders
• Giza North power plant extension gis new 500 kv and 220 kv
• Raas ghareb 500 kv new substation
• Attaqa power plant 4 units gis 220 kv
• EL-Mansheya nasser 220 kv new substation
• ELCO steel new substation 220kv GIS .

The core business of the company is to provide the testing and commissioning services for other companies .

so i was rented to many companies in egypt and KSA

the projects i have worked in

• Quryat power plant 6 modules
• Ansaldo eneregya (6 octobre first stage power plant gis 220 kv )

My role to test all protection relays such as micom ABB &siemens desi 4 relays

verifying the scheme and intel lock and applying the final setting and doing the trip test

trouble shooting and investigating the faults at the Egyption network and evaluating the relays performance

Doing all testing and commissioning activities

• Testing current transformers and voltage transformers .
• Testing Gis component like circuit breakers
• protection relay siemens , Micom &ABB Relays and auto reclosers
