Abstract:
Statistical researches of
failures in medium voltage electrical power
networks, which are constructed as overhead
power lines with ACSR wire, show that most
failures are due to single-phase-to-earth faults,
which under certain conditions can transit into
interphase faults. To reduce the energy not
supplied to consumers proposed to install the
special device in the power network. The name
of this device is the identifier of single-phaseto-earth fault. It is shown that if the device is
installed on supports of the overhead line of
the power network, this can reduce the expected energy not supplied to consumers
(EENS) by up to 32%. Moreover, the shorter
the time it takes to locate the single-phase-toearth fault in the power network, the greater
will be the reduction in the EENS
