Generator Brush Collector Ring’s Arc Flash Hazard, A Safety Concern!

Generator Brush Collector Ring’s Arc Flash Hazard, A Safety Concern!

For some types of generator exciter systems, collector rings and brushes are used to provide energy from the exciter to the rotating field. The brushes wear down and constantly need to be replaced with the unit on-line and while brush/ring assembly is still energized, a risky and unsafe maintenance operation and may cause a serious harm. A potential shock and arc-flash hazard. This presentation addresses the important and dangerous maintenance of worn-down collector rings and brushes, electrical safety, lack of standards and guidelines, and a first possible calculation method.

ZSI Scheme for Protective Device Evaluation & Arc Flash Mitigation Technique using ETAP

ZSI Scheme for Protective Device Evaluation & Arc Flash Mitigation Technique using ETAP

ZSI (Zone Selective Interlock) Scheme has been developed about 40 years ago and since then, the application has expanded from Protection to Arc Flash Hazard Mitigation and even Coordination or Selectivity.

A Comprehensive Approach to Protective Device Coordination

A Comprehensive Approach to Protective Device Coordination

The design, sizing, and regulation of the protection system are still one of the major challenges for the integrity and continuity of operation of the power system despite the continuous technology evolution.  Protection system shall be capable to continuously monitor the power system, operate quickly and selectively under hundreds of transitory conditions for any type of fault without false trips with the objective to minimize outages, improve safety, and maximize service continuity. This presentation covers a real case study for an expansion of a brownfield industrial installation with new equipment that prompted the need for modification of existing protective device settings thus, requiring revision and re-validation of the coordination studies. The case study will demonstrate how ETAP software features and capabilities were utilized to verify the new / recommended settings to address the protection & coordination objectives and arc flash hazard impact.

ABB FCL Application Engineering for IS-Limiters

ABB FCL Application Engineering for IS-Limiters

This presentation will feature covert ABB Fault Current Limiter (FCL) application engineering for Is-limiters. We will explain the fault current limiter technology by using the well-known ABB FCL Is-limiter. The FCL technology will be introduced, how it clears a short-circuit fault current compared to a standard circuit breaker, and the major components of an FCL. The theory of the application engineering process and the calculation of the tripping value for an FCL will be introduced. Based on an actual customer project, it will be shown how ETAP has facilitated the complex FCL application engineering, and examples will be provided of how the real tripping value for a fault current limiter is determined. The session will conclude with an overview of how etap can already be used today for an FCL application engineering and what will be enhanced in the future.
