Getting Started

Installation

Download the zip file, extract to any folder on your computer, and run the .exe file. No installation required, no admin rights needed.

First Launch

On first launch, the splash screen appears with a progress bar. The app initializes the database, loads language files, and applies your theme. All data is stored locally on your computer.

Free Trial Limitations

• Max 3 projects
• Max 10 cables per project
• Max 10 quotation items
• Max 10 terminals per project
• Max 10 devices per project
• Max 2 drawings
• Exports include watermark

Project Management

What it does: Create and organize all your electrical design projects. Every other module works within the context of a selected project.

How to use:

• Click "New Project" to create a new project
• Enter project name, customer, engineer, and description
• Click "Set as Current" to switch to a project
• All data in other modules is automatically linked to the current project

Cable Sizing

What it does: Calculate the appropriate cable cross-section based on load current, voltage drop, and installation conditions.

How it works:

• Enter load power, voltage, power factor, cable length, and installation method
• The app automatically calculates the load current using standard formulas
• It then checks ampacity against standard cable tables
• Finally, it verifies voltage drop and recommends the smallest cable size that meets both requirements

Formulas used:

Results include:

• Calculated load current
• Recommended cable cross-section
• Ampacity check (pass/fail)
• Voltage drop percentage and check
• Warning messages for oversized loads

Load Calculation

What it does: Calculate total electrical load for a building using the demand factor method.

How to use:

• Add individual load groups: lighting, power outlets, HVAC, motors, etc.
• Enter installed capacity, demand factor (Kd), and power factor (cosφ) for each group
• Click "Calculate" to get total load results

How it works:

• Calculates active power: Pjs = Kd × Pe
• Calculates reactive power: Qjs = Pjs × tanφ
• Applies simultaneous factor (default 0.9)
• Calculates apparent power: Sjs = √(Pjs² + Qjs²)
• Recommends transformer size with 20% margin

Panel Configuration

What it does: Design distribution panels, specify breakers, buses, and circuit schedules.

Note: This is a data entry module. Enter your panel configuration details manually. Future versions may include automatic breaker sizing based on load calculations.

Short Circuit Calculation

What it does: Calculate fault current at the main distribution panel and recommend breaker breaking capacity.

How it works:

• Enter transformer capacity (kVA) and impedance percentage (typically 4-6%)
• The app calculates three-phase and single-phase short circuit currents
• It then recommends the minimum breaker breaking capacity with 20% safety margin

Standard ratings: 6kA, 10kA, 15kA, 25kA, 35kA, 50kA, 65kA

Grounding System

What it does: Design grounding systems, calculate earth resistance, and size grounding electrodes.

How to use:

• Enter required resistance (typically 4Ω for general, 1Ω for sensitive equipment)
• Enter soil resistivity (typical values: 50-500 Ω·m)
• The app calculates the number of vertical grounding electrodes needed

Formula used:

Motor Control

What it does: Record motor specifications and control circuit details.

Note: This is a data entry module. Enter your motor control details manually. Future versions may include automatic starter sizing.

Lighting Design

What it does: Calculate required number of lighting fixtures for a room using the lumen method.

How to use:

• Enter required illuminance (lux): 100 for corridors, 300 for offices, 500 for detailed work
• Enter room area (m²)
• Enter lumens per lamp (typical: 2000-5000 lm for LED)
• The app calculates the number of lamps needed

Meter Sizing

What it does: Record main breaker, busbar, and service entrance equipment details.

Note: This is a data entry module. Future versions may include automatic meter sizing based on total load calculation.

Cable Tray

What it does: Record cable tray layout and dimensions.

Note: This is a data entry module. Future versions may include automatic fill ratio calculation.

Lightning Protection

What it does: Calculate lightning rod placement and protection radius.

How it works: Simple rolling sphere method calculation. Enter rod height and protection level to get the protection radius at ground level.

Cable Schedule

What it does: Generate a complete list of all cables with lengths, types, and spare capacity.

Features:

• Enter each cable: start point, end point, type, conductor, cores, length
• Automatically adds 10% spare length for installation slack
• Summary view: total length by cable type
• Export to Excel

Project Quotation

What it does: Create professional quotations with material costs, labor costs, markup, and tax.

Features:

• Material Library: Pre-loaded with common electrical materials (breakers, cables, conduits, etc.)
• Quote Items: Add items from the material library or enter manually
• Import from Device Log: Automatically import all devices from your device log into the quotation
• Pricing Parameters: Material markup %, labor cost, management fee %, tax %
• Auto-calculation: Total cost is automatically recalculated as you add items
• Export: Export to Excel or PDF

Terminal Blocks

What it does: Design terminal block schedules for control panels.

Features:

• Enter each terminal: number, wire gauge, function, destination
• Auto-numbering
• Group by terminal block
• Export to Excel

Device Log

What it does: Track all electrical devices and equipment in your projects.

Features:

• Record device name, model, serial number, location, installation date
• Calibration date tracking with expiry reminders
• Status: in use, spare, out of service
• Import directly into quotation with one click

Drawing Markup

What it does: Import PDF drawings, convert to images, and mark up device locations and cable routes.

How to use:

• Export your PDF drawing to PNG using any PDF viewer
• Import the PNG into Drawing Markup
• Click on the canvas to add device markers
• Right-click a marker to delete it
• Export the BOM list to Excel
