Power Plant Protection & Special applications

PTP engineers have an established background in Power Plant Protection and Special application systems, gained in professional carriers well before establishment of PTP.

We were forerunners in application of Numerical Protection Systems. Among the systems delivered by our engineers prior to PTP were:
1- The very first large scale Generator Protection System (Shahid Abbaspour HEPP, 4 x 250MW machines) done by local experts in 1997.
2- A package of 14 machines (100MW each) in 1999, known as 6 CCPP project.
We are proud of our hard-gained experience from several projects executed within last 15 years, and continue to be the market leader in this field in Iran, and started executing projects abroad.
