CLiP Current Limiting Protector Case Study

This case study examines the implementation of the CLiP Current Limiting Protector by Pedra Agroindustrial S/A, a Brazilian renewable energy company. The company, which has been operational since 1931, transitioned to the renewable energy sector by leveraging waste from sugarcane production to generate electricity. The study details the challenges faced during the planning of two new power plants, particularly concerning the interconnection of the plants and the need for equipment capable of handling high fault currents. Three potential solutions were considered: upgrading existing equipment, utilizing a current limiting reactor (CLR), or implementing the CLiP current limiting protector. The CLiP was chosen for its long-term cost savings, compact design, and enhanced safety features. The case study outlines how the CLiP operates during short circuit events and highlights the significant cost savings and reliability achieved over a 20-year period, ultimately demonstrating the effectiveness of the CLiP in protecting the power plants and ensuring safe operations.
