Crescent Power Systems has partnered with GE Grid Solutions to offer the most complete selection of high-voltage power equipment for your transmission and distribution projects.
With broad coverage across the product spectrum, GE Grid and Crescent Power Systems are committed to providing industry-leading quality and reliability with an optimal balance of performance and cost.
GE offers utilities advanced solutions to improve grid stability and increase efficiency of transmission infrastructure. High-voltage circuit breakers, the heart of power systems, protect electrical equipment and infrastructure, fulfilling operational and safety functions. In normal operation, they carry nominal load currents, and depending on the installation, switch various equipment such as lines or transformers.
With more than 25,000 Dead Tank Circuit Breakers installed and in service around the world, GE Grid is recognized as one of the technological leaders ensuring the reliability and safety of operations at an optimized cost.
GE’s breakers are developed based on the highest standards for performance, ratings, user convenience and reliability. Each GE circuit breaker model is thoroughly tested to meet or exceed the latest IEEE and IEC standards. Further benefits include:
- Unique design that provides optimal performance and lower total cost of ownership
- Manufacturing excellence to ensure the highest quality standards
- Extensive research, testing and proven field experience resulting in enhanced reliability
- Optional features for enhanced system compatibility, digital integration and in-house expertise
