OPERATION

4.4.2.1 MIL-STD-704D TRANSIENT PROGRAMS (cont)

OVER-FREQUENCY TRANSIENT (Program #102)

The power source will produce the over-frequency transient excursion as defined by MIL-STD-704D
(Paragraph 5.2.3.2.1). The power source

must

be configured for a voltage range of at least 115Vrms to

perform this test.

INITIAL CONDITIONS:

= 407 Hz.

, V

= 115 VAC (Nominal Steady-State)

WFa=1, WFb=1, WFc=1
DIRECT COUPLED

TRANSIENT COMMAND SEQUENCE:

Segment 1:

F=425 Hz. Va=115, Vb=115, Vc=115, T=0.0002

Segment 2:

F=425, Va=115, Vb=115, Vc=115, T=1

Segment 3:

F=420, Va=115, Vb=115, Vc=115, T=0.0002

Segment 4:

F=420, Va=115, Vb=115, Vc=115, T=4

Segment 5:

F=410, Va=115, Vb=115, Vc=115, T=0.0002

Segment 6:

F=410, Va=115, Vb=115, Vc=115, T=5
