ATP-EMTP Investigation for Fault Location in Medium Voltage Networks

This paper presents a new fault location (FL) method for medium voltage (MV) networks operating with the neutral solidly grounded or grounded across a small resistance. The FL algorithm is based on the impedance measurement principle and uses the recorded three-phase voltage and current signals as well as the network impedance for the particular symmetrical components – pre-calculated after eac...

Threshold Voltage Mismatch ( VT) Fault Modeling

1 On leave from Polytechnical University of Catalunya, Spain. Abstract A reduced intrinsic threshold voltage (VT) in addition to its variability has a direct impact on circuit design. Worstcase design styles assume that all transistors use the same worst-case VT whose average and standard deviation come from inter-die statistical variations. However, intra-die differences, such as random local ...

Arc Fault Detection in Low Voltage DC System Using Wavelet Transform

The main objective of this paper to detect an arc fault occurring in a low voltage dc system using wavelet transform. As we know arc faults plays a major role in an electrical power system, due to this fire, shocking hazard or system failure of the electrical system or equipment can be happen. It’s very challenging to detect arc fault in a dc system because unlike a ac system a dc system cannot...
