High Voltage Testing

Monitor high voltage equipment to ensure that it is performing reliably and detect energized equipment or cables to help safeguard personnel from shock using these testing tools. High voltage testing, commonly known as hipot (high potential testing), tests to make sure current flow or voltage is at the correct levels, and is important to help identify issues in equipment that can cause it to fail, such as corroded conductors, issues with terminal spacing, or crushed insulation.


For overhead and underground applications, use these voltmeters to safely measure voltages in power distribution systems, verify if conductors are in- or out-of-phase, or determine if a conductor is de-energized prior to grounding. They have large digital displays that are easy to read in varied lighting conditions.


Measure peak line current on overhead or underground distribution voltage and transmission voltage networks for spot-load studies. They have hot stick connections for long-distance testing and a large numerical display that is easy to read in most lighting conditions.

AC Detectors

Keep safe with these detectors, which provide an alert signal when close to live high voltage AC conductors. Use with rubber gloves or hot sticks.

Testers & Detectors

Be alerted to hazardous electric fields or energized electrical equipment by these high voltage detectors.

Extension Hot Sticks

Attach meters or tools to these nonconductive fiberglass hot sticks to help safely perform tasks from a distance. They are commonly used on high voltage wires that are potentially energized such as when checking transmission lines or changing fuses.
