Grounding and ground testing are topics and practices most widely recognized by familiar terms and organizations like Fall of Potential Method, 62 Percent Rule, IEEE and NETA standards and practices, and the National Electric Code® (NEC®). These and other significant contributions to the body of knowledge form the foundation of the subject and its implementation in practice.

Grounding electrodes are typically buried metal objects; rods, interconnected arrays of rods, plates, grids, and various other designs aimed at putting a sufficient amount of metal in contact with the soil so as to safely and efficiently divert unwanted fault currents out of the electrical system and out of the protected facility. Upon construction, there is generally a ground resistance specification that is not to be exceeded. A performance test is run to assure that the system meets spec.

Here you will find Firmware to be loaded into the MPQ1000 and MPQ2000 Analysers. The current update file MPQ_Firmware_1295_OLD_OS.zip contains the update, specific instructions for the MPQ1000 and specific instructions for the MPQ2000. Download the zip file and directly unzip it to a Clean Thumb drive.

VLF Sine Wave 45 Firmware

Effective earthing is essential for the safe operation of wind farms, but accurately measuring earth resistance at these locations presents multiple challenges. Ahmed El-Rasheed from Megger, explains how Megger and SSE are working together to address these.

This application note gives examples on how to perform some typical tests on current transformers (CTs) with SVERKER 900. These tests are common to perform for instance during commissioning.

The ‘neon screwdriver’ type of voltage tester has been used by many electricians over the years as a means of checking whether a circuit is live or dead.
