Abstract
Switching operations of circuit breakers and disconnect
switches generate transient currents propagating along the
substation busbars. At the moment of switching, the busbars
temporarily acts as antennae radiating transient
electromagnetic fields within the substations. The radiated
fields may interfere and disrupt normal operations of
electronic equipment used within the substation for
measurement, control and communication purposes. Hence
there is the need to fully characterise the substation
electromagnetic environment as early as the design stage of
substation planning and operation to ensure safe operations of
the electronic equipment. This paper deals with the
computation of transient electromagnetic fields due to
switching within a high voltage air-insulated substation (AIS)
using the finite difference time domain (FDTD) method
