If a Vudar ship is displaced by the andromedans displacement device is the IPG device since it is used in defensive fire phase of a turn still allowed to be used during the impulse turn that a ship is disrupted for defensive jamming?

I don't see anything that would affect the use of an IPG during its impulse of disruption after a displacement. So, yes, it can be used.

I'd thought they were disrupted, the fact that it is used in the defensive phase isn't relevant for disruption of stuff by disdev.

what about ESGs then? does that mean they can still be used as well.

IPGs are not affected as they aren't a "weapon" that is "fired" as such. They are defense systems, and are therefore not affected by being disrupted.

ESGs, in offensive mode, are specifically identified as being a direct-fire weapon in (5N2d). So, the offensive mode of the ESG cannot be used while disrupted. However, the defensive and anti-hellbore modes can be used while disrupted. Those modes are, like the IPG, purely defensive systems, and not affected by being disrupted. (And the ESG defensive mode is explicitly exempted by (5U4b3), regardless.)

The longer explanation is that displacement only disrupts the "fire control" of a ship. (Something that was abstracted out in Federation Commander.) That means, anything that needs the ship to be able to "see" to use (firing or launching weapons; tractors, transports, labs) can't be used. Defensive fire is allowed as it is all so close. But, anything that doesn't need to "see" (i.e. doesn't need fire control) isn't affected by being disrupted. IPGs and the non-offensive modes of ESGs don't need to be able to "see" to work, and so aren't affected by being disrupted.
