P&C Engineer Tools is the ultimate utility for protection and control engineers, relay technicians, and power system professionals. This all-in-one toolbox allows you to perform complex calculations and verify protection settings directly from your device. Key Features: . Symmetrical Components: Easily convert between Phase (ABC) and Sequence (012) values. Visualize phasors with dynamic vector graphs and analyze unbalanced fault conditions. . Distance Protection (21): Analyze impedance characteristics, calculate test values (Reach, MTA, Time), and visualize protection zones on the R-X diagram. . Differential Protection (87): Visualize differential slope characteristics, verify operating points, and check restraint currents. . CT Saturation: Analyze Current Transformer performance using IEEE C37.110 standards. Calculate Time-to-Saturate and assess saturation risks. . Power Vector Tool: visualize voltage and current phasors, and calculate Real (P), Reactive (Q), and Apparent (S) power. Designed for efficiency in the field or the office. Disclaimer: This software is for educational and reference purposes. MARDEVELO does not take responsibility for any errors the program may have. Always verify critical calculations manually.
