• Electrical system testing — This test lead is used extensively in electrical substations, power plants and industrial facilities to ensure system reliability and safety by detecting faults and verifying system performance.
• Installation and commissioning — Utilised during the initial setup of electrical systems, the Pfisterer Test Lead Size 2 facilitates the safe and efficient verification of component functionality and system integrity before full-scale operation begins.
• Quality assurance — This device is used to confirm if all electrical installations meet stringent standards and regulations, safeguarding against potential failures.
• Power Frequency Withstand Testing — This evaluates insulation strength by applying a high voltage at the system’s power frequency for a set duration to ensure equipment can handle operational electrical stresses.
• Tan Delta Dissipation Factor Testing — This measures dielectric losses in the insulation to assess its overall condition and identify degradation or potential failure points.
• Partial Discharge Testing — This test detects and measures electrical discharge in high-voltage equipment, such as transformers and gas-insulated switchgear, providing early indicators of potential breakdowns.
• Emergency and repair services — In emergency repairs and services, this test lead helps technicians quickly identify issues and restore normal operations. This helps minimise downtime and enhance overall system resilience.
