Logistics and network
Supplying Goa.
Deliveries across Goa start at about 1870 km by road, which puts the nearer cities (Panaji, Vasco da Gama, Margao) within 7 days of dispatch. The state's demand centres on Verna and Kundaim industrial estates, Mormugao port, pharmaceuticals.
Distribution in Goa is handled by Goa Electricity Department; Goa Electricity Department runs the transmission network. Programmes now in execution include RDSS, and each is tendered against a technical specification that we quote and manufacture to.
The power transformer line closed the last gap in the chain. Between distribution and power class we now cover 16 kVA right through to 20 MVA — a span very few regional manufacturers hold on a single site.
The standard substation build is 33/11 kV, Dyn11, ONAN, with an off-circuit tap changer at +5% to −10%. Where the network needs voltage regulation under load we fit an on-load tap changer at +5% to −15%, and where the load profile justifies forced cooling we supply ONAF with a rated output at each cooling stage.
