Abstract: A method and analyzer device are provided for testing a power distribution system of a power supply network. A first electrical signal is transmitted into the power distribution system to be tested, the first electrical signal is propagated along the power distribution system to be tested, and a second electrical signal, which is a portion of the first electrical signal reflected within the power distribution system, is received.
