Many electrical devices can be found in households in particular. If their cables or conductors are damaged, this could have fatal consequences for the user in the worst case. To prevent this, protection class I devices have a protective earth (PE) conductor for electrical safety. All the conductive elements within the device must be connected to the PE conductor. This also includes the housing.

The task of the PE conductor is to earth the parts that can be touched in the event of an insulation fault. In the event of a fault, the short-circuit current would flow through the user's body to earth, which can lead to serious injuries or even death. The PE conductor connection dissipates the fault current to earth and thus protects the user.

Before a device is delivered, the PE conductor resistance must be checked. Devices with a PE conductor belong to protection class I. ELABO is specialised in the development of high-quality measuring devices for PE conductors.

ELABO offers different devices for testing PE conductor resistance. The main differences between them are their different measuring ranges. The following gradings are available for the different categories:

• Test voltage: 6 VAC / 10 VAC / 12 VAC
• Measuring range: 200 / 300 / 350 Ohm
• Test current: 25 A / 10 bis 25 A

Depending on the standard requirements of the devices to be tested, various measuring devices are offered. ELABO offers all measuring devices for PE conductor resistance in combination as a complete variant with a housing for mobile use or as a slide-in variant for a test equipment cabinet. This allows the testing station to be set up or expanded as required.
