Special Testing Devices – Voltage Testers
Special testing devices in the field of voltage measurement are specially developed test systems for demanding applications such as high-voltage or custom installation testing. They offer tailored measurement and test configurations, e.g. customer-specific voltage and current ranges, mobile test rigs, automated test programs or advanced safety systems. These devices are used in power supply networks, rail systems, wind farms and other large industrial installations.
FAQ
What defines a “special testing device” in voltage testing?
A special testing device is not a standard voltage tester but a customized solution with enhanced functionality such as higher test voltages, larger test currents, automated test sequences or dedicated test stations for industrial use.
Which test and measurement parameters are typical?
Typical parameters may include voltages ranging from several kilovolts to tens of kilovolts, test currents into the high-ampere range, voltage ramp functions, automatic fault detection, remote control or data logging capabilities.
Which applications are particularly relevant?
Key application areas include power distribution systems, test benches for electrical equipment, large-scale systems such as wind farms or rail vehicles, and mobile test units for on-site verification.
What selection criteria are important?
Important criteria include test voltage and current ratings, measurement and ramp functions, automation interfaces, safety features like fault monitoring and shutdown, mobility or fixed-station design, and calibration/service options.
How are maintenance and documentation managed?
Special testing devices require regular inspections, functional and sequence tests, calibration according to manufacturer specifications and comprehensive documentation of test results to ensure process reliability and traceability.
