(i). Horizontal Busbars = 0.0724x300x3x2.4 = watts
(ii). Vertical Busbars = 0.0724x300x3x2x1.8 = watts
Therefore, total heat loss for Busbars = KW
Therefore, total heat loss for AC Preferred = KW
Supply Panel
6 Battery Charger
Heat loss (watts) = 0.05 x Rated output (Assuming Efficiency of Charger as 0.95)
Rated output of Charger = KW
(As per DC System sizing calculation)
Therefore, heat loss for Battery Charger = KW
7 Marshalling KIOSK-2 DCDB
(a). Incomer module with 400A MCCB:
3 Nos. incomingfeedwers & 1 No. Bus-coupler feeder of 400A MCCB, having 2 CT's of
15VA burden, 5 indicating lamps, 4 meters, 1 PT-100 VA burden, 4 auxiliary contactors &
4 relays
Breaker loss = watts
CT+PT = (2x15+100)x0.1 = watts
Indicating lamps = = watts Negligible, since the type
Meters = 4x3 = watts of indication lamp is
Aux. contactors = 4x4 = watts assumed as LED type
Relays = 4x2 = watts
The heat loss one outgoing feeder = watts
Therefore, total heat loss for 4 feeders = KW
(b). Outgoing module with 32A MCB: = KW Assumed
Busbars with 1 No. of 400A horizontal & 2 Nos. of Vertical drop inside the panel(i). Horizontal Busbars = 0.0724x400x2x3.6 = watts
(ii). Vertical Busbars = 0.0724x1000x2x2x1.8 = watts
Therefore, total heat loss for Busbars = KW
Therefore, total heat loss for Marshalling = KW
KIOSK-2 DCDB
Therefore Total Heat Load For Marshalling = KW
