Is Your Building an Electrical Death Trap?

Voltage Leakage: The Silent Killer

One of the most dangerous electrical problems is voltage leakage—also known as ground faults or leakage current. This occurs when electrical current finds an unintended path to ground, typically through your body when you touch an outlet, switch, appliance, or even the metal frame of equipment. Many people describe this as a tingling sensation or a mild electric shock, but it's far more serious than it sounds.

Voltage leakage happens gradually over time as wiring insulation deteriorates, connections corrode, or moisture infiltrates electrical systems. A small leak might feel like a gentle buzz, but it indicates that your entire electrical system is compromised. If you experience any of these warning signs, your home or business is in danger:

• Electric shocks when touching outlets, light switches, or metal appliances
• Tingling sensations in your fingers or hands when near electrical equipment
• Burning smells near outlets or from walls, indicating overheating wires
• Scorch marks or discoloration around outlets, switches, or junction boxes
• Flickering lights that suggest unstable voltage or poor connections
• Frequent circuit breaker trips without obvious overloading
• Warm or hot outlets to the touch, indicating excessive resistance
• Buzzing or humming sounds from electrical panels, wiring, or transformers

These are not minor annoyances—they are red flags for serious electrical hazards. Voltage leakage can cause fire, electrocution, and damage to expensive equipment. It's particularly dangerous for children, elderly people, and anyone with heart conditions or pacemakers, as even mild electrical currents can trigger fatal arrhythmias.

How We Diagnose and Fix Electrical Hazards

At Keystone Technologies, we use advanced diagnostic equipment to identify voltage leakage and other electrical problems before they become catastrophic. Our certified electricians perform thorough testing using specialized tools like insulation testers, ground resistance meters, and thermal imaging cameras that reveal hidden problems invisible to the naked eye.

Our comprehensive approach includes:

• Voltage Leakage Detection & Repair: We locate the source of leakage current using precision testing equipment, then repair or replace damaged insulation, corroded connections, and faulty components. We ensure proper grounding throughout your entire electrical system.
• Ground Wire Testing & Installation: A properly functioning ground system is essential for safety. We test your grounding infrastructure and install or upgrade ground wires to meet current electrical codes and safety standards.
• Thermal Imaging Inspections: Using infrared cameras, we scan your electrical panel, wiring, and connections to detect hotspots indicating failing components, loose connections, or excessive resistance before they cause fires.
• Damaged Wiring & Outlet Replacement: We replace corroded, outdated, or damaged wiring with modern, code-compliant electrical systems. Old cloth insulation, aluminum wiring, and brittle copper all get replaced with safe alternatives.
• Circuit Load Balancing: Uneven load distribution causes some circuits to be overworked while others sit idle. We balance your electrical load to prevent breaker trips, reduce fire risk, and improve efficiency.
• Safety Upgrades & Modernization: We install modern safety devices like GFCIs (Ground Fault Circuit Interrupters), AFCIs (Arc Fault Circuit Interrupters), and surge protection systems that prevent electrical accidents before they happen.
• Complete System Restoration: For severely compromised electrical systems, we perform complete rewiring and modernization, bringing your building up to current electrical codes and safety standards.
