ETAPValidation Cases and Comparison ResultsETAP is Verified and Validated (V&V) against field results, real system measurements, published cases, otherprograms, and hand calculations in order to ensure its technical accuracy. Prior to each release, to encompass theV&V of new features and capabilities, the ETAP Test Group adds new test cases to the existing battery ofscenarios. In addition, the Test Group re-runs all existing test cases, as part of our extensive and comprehensiveV&V process.In accordance with OTI's Quality Assurance Program, all procedures and activities related to the quality ofETAP software are subject to internal and external audits, including nuclear clients and ISO 9001:2000certification assessments. Test cases are reviewed during the audit process.This document includes:Load FlowLoad Flow Comparison Case #1Comparison of ETAP Load Flow Results against a Published Textbook ExampleLoad Flow Comparison Case #2Comparison of Load Flow Results against a Published ExampleLoad Flow Comparison Case #3Comparison of ETAP Load Flow Results against Published Textbook ExamplesShort-CircuitShort-Circuit ANSI Comparison Case #1Comparison of Short-Circuit Results against Hand Calculations based on Application EngineeringInformationShort-Circuit ANSI Comparison Case #2Comparison of ETAP Unbalanced Short-Circuit Calculations against a Published ExampleShort-Circuit ANSI Comparison Case #3Comparison of ETAP 3-Phase Duty Short-Circuit Calculations against Published IEEE Std 399-1997ExampleShort-Circuit IEC Comparison Case #1Comparison of ETAP Short-Circuit IEC Calculations against Published ExampleArc FlashArc Flash Comparison Case #1Comparison of ETAP Arc Flash Results against hand calculated results based on IEEE StandardsArc Flash Comparison Case #2Verification of ETAP Arc Flash NFPA 70E results against Hand Calculations
