Grounding measurement – An earth fault is a term from electrical engineering. It describes an unwanted connection between a conductor that carries voltage and the earth. In case of a short circuit, the fault is easy to find due to the high current flow. This is not the case with an earth fault. Here the fault current is usually much lower than in a short circuit. Therefore, the location of the fault is much more difficult to find. The earth fault measurement is indispensable to detect ohmic or specific earth resistance. It is an important task for the electrician.
Precise measurement can improve the quality of electrical installations. The ground fault measuring instruments offer many functions in a sturdy housing. The handling of the earthing test clamps or earth measuring instruments from WGM Support is very easy. They are important test instruments for earth measurement. They are suitable for a variety of applications. Convince yourself.

In the field of electrical engineering, an earth fault is a fault with a high risk potential. An earth fault is a fault situation in which one phase conductor is in contact with the earth. Consequently, a power supply system where the neutral point is grounded is called an earth fault. In the case of an earth fault, electrical current flows to earth, resulting in an earth short circuit.
The grounding test family DET4 from Megger offers comprehensive solutions for your grounding measurement requirements. Therefore, you have everything you need for your measurements. The standard equipment consists of the tester, test cables, electrodes, connection adapter set and batteries. The earth measurement kit is supplied in a carrying case. The DET4TC and DET4TCR ground testers are designed for use over a temperature range and have an IP54-rated housing. This allows the test instruments to be used outdoors without compromise. The Ground measuring DET4TCR has all the functions for earth testing. As a result, the tester offers variable frequencies from two to four conductor measurements and more.
The instrument has no hidden functions. Therefore, switching the backlight on and off is very easy. That way it is possible to operate both functions with the gloves. Consequently, it uses unique auxiliary controls to select the test frequency or the output voltage. Fifty or twenty-five volts, depending on local standards. Therefore, the design does not require a short circuit connection when performing two pole measurements – unlike other instruments. The Ground measuring DET4TCR is powered by standard AA batteries. This allows for an excellent operating time during the measurement.

The Ground measuring DET24C earth leakage tester is a digital earth tester and offers a possibility for accurate RMS current measurement. The DET14C and DET24C ground testers allow you to measure without seperating the earth electrode, increasing measurement integrity and reliability over products with interlocking teeth. Other improvements over current generation products include improved accuracy and up to three hundred percent longer battery life. In electrically noisy environments, the built-in filter function provides increased immunity to interference. The unit’s ability to measure the current flow in an underground cable is a useful safety feature, especially when the ground cable needs to be disconnected.
The Ground measuring DET24C and DET14C ground testers represent a new generation of clip-on ground testers. These devices induce a test current into grounded systems and measure the ground resistance in multi ground installations without disconnecting the ground connection. They offer access, advanced features, ease of use and CAT IV 600V safety protection. They feature flat jaws and prevent dirt build-up, increasing measurement integrity and reliability over products with interlocking teeth. Other improvements over current generation products include improved accuracy and up to 300 percent longer battery life. In electrically noisy environments, the built-in filter function provides increased immunity to interference.
