🔧 8 TOOLS IN ONE APP:
⚡ CABLE SELECTION
Calculate the wire cross-section (Cu/Al), select the overcurrent protection (B/C/D), and check the voltage drop. Cross-sections 1.5–240 mm², 5 mounting methods, 1F (230V) and 3F (400V) networks.
Standard: PN-HD 60364-4-43, PN-HD 60364-5-52
🔍 CHECK YOUR EXISTING CABLE
You have a cable—what can it handle? Enter the cross-section, material, length, and routing method—and you'll receive the maximum load (kW) and the largest permissible fuse rating. Standard: PN-HD 60364-5-52
🔄 POWER CONVERSIONS (kW ↔ A ↔ kVA)
Quick conversion between active power, current, and apparent power. Single-phase and three-phase networks with cos φ adjustment (presets: motor, lighting, welding machine, household appliances).
🔌 HOW TO POWER THE DEVICE? (OCR)
Scan the nameplate with your camera—OCR will recognize P, U, I, cos φ, Hz, and rpm. Automatic cable and fuse selection. You can also enter data manually.
Standard: PN-EN 60034
📋 SWITCHGEAR DESCRIPTION GENERATOR
Create switchboard cell descriptions (RG, RP, apartment boards). Set module widths, move components, and export to PDF. Portrait/landscape orientation. 📐 SWITCHGEAR DIAGRAM (IEC 60617)
Single-line diagram editor. 28 component types in 8 categories: circuit breakers, RCDs, RCBOs, SPDs, contactors, relays, timers, lamps, terminal blocks. Export to PDF with company footer and descriptive table.
Standard: IEC 60617, PN-HD 60364
📊 MEASUREMENT PROTOCOLS
Protocol creator compliant with PN-HD 60364-6. 12 measurement types (visual inspection, PE continuity, insulation, short-circuit loop, RCD, grounding, phase sequence, voltage drops, SPDs, EMC, and more). Automatic result evaluation, electronic signatures, photos, export to professional PDF. Standard: PN-HD 60364-6, PN-EN 61557
💡 LIGHT METER (LUX)
Real-time illuminance measurement using a phone sensor. HOLD function, MIN/MAX/AVERAGE statistics, and classification according to the standard. Approximate results.
Standard: PN-EN 12464-1:2021
