High-Voltage Testers
High-voltage testers are used to safely verify systems, lines and components that operate with high AC or DC voltages, typically ranging from several kilovolts up to several tens of kilovolts. They detect voltage relative to earth, indicate AC or DC presence, and provide clear visual and acoustic alerts. Many devices feature insulated and extendable test probes to maintain safe working distances in high-voltage environments.
FAQ
What are high-voltage testers used for?
High-voltage testers are used to check for voltage in high-voltage systems, overhead lines, medium- and high-voltage installations, switchgear and designated test points where reliable indication of voltage to earth is required.
What voltage ranges do high-voltage testers cover?
Typical voltage ranges start at a few kilovolts and extend beyond 30 kV depending on the device. Some testers are specifically designed for networks up to 36 kV or higher.
Which safety and indication features are important?
Key features include automatic AC/DC detection, clear optical and acoustic warning signals, built-in self-test functions, high insulation strength and extendable or telescopic probes to ensure safe distancing during measurement.
What must be considered during use?
Test points must be properly exposed, and required safety distances must be observed. The device should be checked before and after use, applied according to the operating instructions and used only when fully functional.
Which standards and regulations apply?
Relevant standards define requirements for safe operation of electrical installations, insulation levels, voltage detection and safe working procedures. General electrical safety rules must also be followed when using high-voltage testers.
