Execution of the dynamic test
GUID-FF6DCD5B-96AA-4255-8740-B85C8C7148F5 v1
The test may be performed by using two states of a sequence tool that is a basic
feature of test sets.
• State 1: pre-test condition.
Steady voltage and current are applied in order to get a steady high impedance,
that is a point in the plane R-X which is far away from the lens characteristic.
Define the following three-phase symmetrical quantities (the phase angle is
related to phase L1):
