Verifying Earth Fault Loop Impedance (EFLI) The ECA (Electrical Contractors Association) presented their latest technical guidance as part of a CPD training presentation for their Midland area members. The training was supported by Power Quality Expert who helped to explain how metering accuracy is calculated and how this accuracy of test meters is important when [...]
Measuring short circuit loop impedance at solar farms and photovoltaic power plants With the increasing and dynamic development of solar photovoltaic farms and power plants, we are witnessing a growing demand for proper short-circuit loop impedance measurement between the inverter and the LV/MV transformer. To enable these tests to be made, Sonel have developed the [...]
Short Circuit Current Testing of Distribution Installations with High Current Fault Loop Impedance Meters The use of electrical installations and devices may pose a risk of electric shock, especially if there is damage to the power supply circuit or the equipment powered from it. Protection of people in the immediate vicinity of electrical devices in [...]
