- Occurrence of harmonics in the residual earth fault current of electricity distribution networks
MENKI
Measurement methods for earth-fault currents in 110 kV networks using complex impedance networks
In order to obtain the required measurement data in 110 kV networks without running the risk of a double earth fault, the MENKI project is developing a method in which a condition similar to an earth fault is created using the voltage transformers present in the substations and a measurement circuit connected to them. This should make it significantly easier to transport the measurement equipment used.

CODICES
Condition Diagnosis of Earthing Systems
Integrated condition monitoring of distributed earthing systems: The aim is to develop an active electrical measurement method that enables the progression of corrosion – and thus the condition of the earth electrode – to be assessed. Building on this measurement method, a measurement system is to be developed that handles data pre-processing and transmission. To enable the generic use of this new approach, a specialised IoT device (Industry 4.0 component) is being developed and tested as a prototype.

Project duration: 2020–2022
FERD
Frequency-selective earth fault
The high reliability of supply in German distribution networks is largely determined by their ability to demonstrate a high level of fault tolerance in the face of one of the most common network faults: earth faults. To minimise the risk of grid outages, the frequency-selective earth fault protection system was developed in close collaboration with MITNETZ Strom GmbH.
