Graphic Electricals

• Cable fault locator • Surge generator (Thumper) • TDR (Time Domain Reflectometer) • Insulation resistance tester (Megger) • Earth fault loop impedance tester • Acoustic fault locator

If you’re facing unexplained power outages, tripping breakers, or voltage irregularities, the problem may lie underground. At GRAPHIC ELECTRICALS, we specialize in advanced underground cable fault detection for residential, commercial, and industrial networks.

Pinpointing cable faults (open circuit, short circuit, earth fault, insulation breakdown). • Identifying exact fault location with minimum excavation. • Reporting findings and recommendations.

• Quick Fault Location: Using cutting-edge technologies like TDR, Thumper, and Acoustic Detection, we pinpoint the exact location of faults—saving you time and costly excavations. • Minimal Disruption: No guesswork, no unnecessary digging. Our methods ensure accurate detection with minimal impact on your property. • All Cable Types: We handle low, medium, and high voltage cables with expertise.

Fault Detection MethodsThe service provider must utilize appropriate fault location techniques based on cable type and fault nature, including: • Time Domain Reflectometry (TDR) • Thumper Method (Surge Generator) • Murray Loop and Varley Loop Tests • Impulse Current Method • Acoustic and Electromagnetic Detection
