he input to the circuit is applied from the regulated power supply. The a.c. input i.e., 230V from the mains supply is step down by the transformer to 5V and is fed to a rectifier. The output obtained from the rectifier is a pulsating d.c voltage. So in order to get a pure d.c voltage, the output voltage from the rectifier is fed to a filter to remove any a.c components present even after rectification. Now, this voltage is given to a voltage regulator to obtain a pure constant dc voltage

sources, such as wind turbines and PV-systems. Also the combined heat and power
production is encouraged. This has lead to an increasing penetration of small gen-
erating units in medium voltage (MV) grids. Small generation units, also distrib-
uted generation (DG), can have a significant impact on power flow, voltage profile,
power quality and grid protection. In this article the effect of DG on grid protection
is studied in detail. The paper gives an overview of current protection practices in
MV-grids and shows how these practices are influenced by DG. A procedure is
