E-02 Transient Overvoltage Pulse
Transient overvoltages may occur in the electric system due to the switching off
of loads and due to short accelerator tip-ins. These overvoltages are simulated
by means of this test. This test may be used for the electrical life test. The test
pulse of E-02 Transient overvoltage is shown in the figure below:
