Hi all,
Are Battery racks/packs and inverters or dedicated small ups replacing the Emergency kit fittings?
I have been looking at latest designs and its of concern that the emergency lighting is currently seen in terms of the time limit before the backup (standby Genset comes up) which literally means, the emergency lighting is vaguely seen as having a few luminance so that we don't remain in total darkness and not in the sense of safety in case of fire.
Of course this new trend also comes with the problem of having two sources at possible different voltage levels or from different phases in the same room at both high and low levels and having 2 consumer units at each location plus the distributed cabling and the switching, conduits through the walls/cavities.
How does this affect the harmonic levels in the system?
Are there any EMC problems related to the approach?
How are you people dealing with this kind of problem/ trend and is this the right way or is cost saving taking over the industry?
