CALCTRON PRO

Protection Study for Enclosed Substations and Low-Voltage Sizing.

CALCTRON PRO has evolved from a cable calculation tool to become one of the most complete software programs for Android. Now, in addition to precise low-voltage sizing, you have the power to perform Protection and Selectivity Studies (ANSI 50/51) and CT Saturation Analysis, generating graphs and reports ready for approval by utilities or audits.

Save hours of work, eliminate complex desktop software, and demonstrate immediate technical authority with safe and integrated decisions.

The Power You Are About to Acquire

1. Complete Low-Voltage Report

Conductor Sizing: Define phase and protection gauges (#PE) considering the conductor/insulator type (Copper/PVC), number of conductors per pole, and voltage drop limit.

Automatic Correction Factors: Agile application of reference methods, grouping factors, and ambient temperature correction.

Thermal Safety and Short-Circuit: Calculate the three-phase short-circuit current (Icc3) at the transformer terminals and in the LV switchboard. Evaluate cable withstand capability using Joule Thermal Damage and validate the circuit breaker capacity.

2. Protection Coordination and Selectivity (ANSI 50/51)

Relay Parameterization: Precisely adjust the time-delayed (51) and instantaneous (50) functions for Phase and Neutral, defining the starting current, Dial, and inverse time curves (IEC).

Automatic Graphic Coordination Diagram: Visualize the exact coordination between the relay curves (phase/neutral), the high-voltage fuse link, and the transformer inrush curve.

Support Points: Visually monitor the system's safety margin relative to the transformer's ANSI and NANSI points.

3. Advanced CT Saturation Analysis

Real Burden Calculation: Sum the exact impedance components of the interconnecting cables, the relay's nominal operating regime, and the current transformer itself.

Accuracy Validation: The app calculates the internal saturation voltage under fault conditions (Icc3) and compares it with the CT's nominal nameplate voltage, ensuring correct protection operation according to IEC standards.

High-Value Technical Reports in Seconds

Forget about manually assembling calculation reports. CALCTRON PRO generates professional reports in export-ready PDF format, presenting:

Organized nominal installation data and input parameters.

Detailed, auditable, and traceable calculation reports.

High-resolution plotted selectivity coordination diagram.
