Short circuit impedance
Before operating the instrument, make sure that the safety rules have been fully
read and understood. It is the responsibility of the end user to ensure that the
system is operated in a safe manner.
14.4.2 Transformer connection
To perform a short circuit impedance measurement, the other transformer side (normally the low
voltage side ) must be short circuited with short and high current (low inductance) connections.
As the resistance is multiplied with the square of the ratio while measuring from the
other transformer side, it is critical to keep the short circuit connection resistance as
low as possible to avoid adding unnecessary error to the measuring circuit.
