Experimental Validation of a Low-Voltage Regulator Model – Case Study of a Maltese Low-Voltage Grid

This application report addresses the integration of the »LVRSys® Low-Voltage Regulation System« into the low-voltage grid in Malta.

Cost Efficient Management of Digital Secondary Substations: Earth Fault Indicator EOR-3DS as Digitisation Unit for Secondary Substations

Digital secondary substations are becoming a key element for distribution system operators in terms of automation, monitoring, and efficient operations of their networks. Read this technical report about the EOR-3DS in its role as digitisation unit for secondary substations.

Ferrari´s Meter vs. Electronic Meter

This technical report analyzes a power measurement at a large industrial customer. The customer records very high currents and fifth harmonic voltages during production time, which leads to poor voltage quality.

Angle determination of voltage and current harmonics in practice

Today’s devices and equipment such as switched-mode power supplies, frequency converters, regulated drives, charging devices for e-mobiles or LED lighting work internally with high clock frequencies in order to regulate power efficiently. These can lead to both conducted and field-bound (coupled) influences in the energy grid. In this technical report, we explain how you can detect these sources of interference in the grid using suitable measuring technology.
