بررسی اقتصادی تولید پراکنده

ABSTRACT: This paper introduces a new method for economical analysis of the using of distributed generation (DG) in the industrial plant instead of purchasing power and heat production in traditional method.In this financial model, the investment costs of traditional method for supplying heat and power in construction period and power and heat production costs in productions years must be disburse in absent of cogeneration enter as subsidies or grants respectively in construction and productions years

An AC motor

An AC motor  is an electric motor driven by an alternating current (AC).It commonly consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field.There are two main types of AC motors, depending on the type of rotor used. The first type is the induction motor, which […]

POWER TRANSFORMER MAINTENANCE…

This manual contains a generalized overview of the fundamentals of transformer theory and operation.The transformer is one of the most reliable pieces of electrical distribution equipment (see figure l-l). Ithas no moving parts, requires minimal maintenance, and is capable of withstanding overloads, surges,faults, and physical abuse that may damage or destroy other items in the circuit. Often, the electrical event that burns up a motor, opens a circuit breaker, or blows a fuse has a […]
