Testing HV Equipment

By Aaron O'Sullivan


Working with electrical equipment can be a dangerous task, and when it comes to using electronics in the workplace most companies have the safety of their employees at the forefront of their minds.

Live wires are one of the most dangerous aspects of working with electricity, and this problem comes to the forefront when electricians are trying to fix faults with electrical wires, as they are frequently unsure as to if they are dealing with live electricity. If the correct precautions aren't taken this can lead to electrocution.

Over time, companies have developed a wide range of High Voltage Test Equipment aimed to help ensure the safety of workers within the electrical industry. Designed to measure the current flowing through a certain wire, the Equipment can then alert the user to the presence of any electricity throughout the repair process.

High Voltage Testing Equipment ranges from expensive, high end brands which provide detailed readings on the type, source and level of current running through an item, to your basic handheld device, which by using its pen shaped end can tell you whether a current is present in a device - this item is a common staple in any electrician's toolbox. These basic handheld devices allow electricians to quickly and safely monitor if there are live wires in the area that they will be working, so they can avoid electrocution.

The Halo Hook is another tool commonly used by electricians, particularly if they are working on overhead power lines. Encased in a safe plastic casing to ensure the safety of the user, this tool is able to measure up to 40kV of power on an overhead line. Complete with an easy to read digital display, these devices can give a range of readings to the user and alert them to any current that is present, and where it is present. These readings can then be stored in the device for further analysis if necessary, or if something needs to be checked further down the track.
