## Description

The complete field companion for Protection & Control Engineers. Perform complex calculations for Symmetrical Components, Distance, Differential, and CT Saturation.

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.
