Steam-based heating processes use latent heat and transfer it to a given product. When the work is done (i.e. steam has given up its latent heat), steam condenses and becomes condensate. In other words, condensate does not have the ability to do the work that steam does.
Subtransmission is part of an electric power transmission system that runs at relatively lower voltages. It is uneconomical to connect all distribution substations to the high main transmission voltage, because the equipment is larger and more expensive.
â¢ Both transmission and distribution refer to movement of power after it has been generated at the power plant but whereas transmission is the movement of electricity from power plant to power sub stations near populations, distribution refers to carrying electricity from this sub station down to end consumers.
