This document provides an overview of the design and construction features of hydro turbines and valves manufactured by BHEL. It discusses how BHEL entered
The design challenge has two possible tracks: generating a holistic design of a hydroelectric power plant or creating a detailed design of a
The equivalent 65'C two-winding parts to be used in calculating the loss product factor is the 65'C self-cooled Kva two-winding parts of a transformer specified to deliver the required output Kva at an average winding tempera-. In calculating the loss product factor and loss ratio for a power transformer the following. The percent no load loss (%Fe) and the per- The evaluation S.'kw for no-load and load los-cent load loss (%Cu) may be determined from ses will affect the optimized design losses of athe final product factor IP) and the loss ratio transformer. (a) Guide Specification CE-2203 states the following: In the evaluation of Transformer Auxiliary Power, the power required for motor-driven fans and oil-circulating pumps should be evaluated on the basis that each horsepower of motor rating in excess of the number of horsepower excluded from evalua-tion is equal in value to approximately 40 percent of the capitalized value of one kW of loss used in the transformer efficiency evaluation.
This highlights the importance of developing a Pico Hydro trainer that can be used as a laboratory tool in engineering education (Azis & Fitri,

Micro-hydro systems generally consist of the following components: • A trash rack, weir, and forebay to pre-vent debris from entering the pipeline and turbine • A pipeline (also called a penstock) to pipe water to the turbine • A powerhouse that contains the turbine and electronics • A water turbine that converts the kinetic energy of the fl owing water into mechanical energy that can be used directly or to drive a generator or other piece of equipment—this is the main component of a micro-hydro system • A tailrace to release the water back into the source it came from • Transmission lines to deliver electrical power where it is needed Th is publication is intended to include as much information as necessary to get you started in the process and to assist you generally at each step along the way of a micro-hydro project.
