power systems loss

How can we estimate the distribution feeder loss using a single formula? The distribution system of an electric utility is a very complex system that is composed of many different kinds of electrical equipment. To mention a few of these components, this would include the feeder lines or wires which in reality are of different size and lengths, distribution transformers of different kVa rating capacity, low voltage lines, etc. 

BREAKING DOWN SYSTEM’S LOSS COMPONENTS TUTORIALS How Electric Utilities Compute for the overall system’s loss value? We have discussed in our previous topics the main components in computing for the system’s loss of a typical electric utility namely the Purchased, Sold and Company use kilowatt-hours. The main principle behind the determination of system’s loss revolves mainly in the amount of unaccounted kilowatt-hour loss in comparison to the total kilowatt-hour purchased. Electric Utilities system’s loss differs from one another due to the reason that each utility possesses a unique network of electrical system. Some may have a dense loading profile while others may have relatively scattered loads. The usual reason why some utilities have higher line loss can be explained by the presence of over-extended lines just in order to serve customers in the remote area. Most electric utilities/cooperatives are supplied with electricity from more than one source to ensure rel...

(From npsc2010.uceou.edu ) The performance of transformer, the most ancient power system static element, is affected due to presence of distortion in the input supply voltage and non-linearity in the load current. Due to extensive use of modern power electronics controlled devices, the degree of non-linearity in the load current has increased in recent years. 

How to compute for the losses in transmission lines? Losses in the transmission lines can be determined less complicated compared to transformers and  distribution systems . The basic computation of it usually surrounds to the fundamentals of ohm's law . Due to the simplicity of the transmission line configuration, solving for its line losses requires no advance knowledge in any electrical principles. However, there are also portion of these line losses that better understanding is necessary. 

What is the use of power factor in power system? Power Factor is defined in the fundamentals of electrical engineering as the cosine of the phase angle between the voltage and the current. An inductive circuit is said to have a lagging power factor , and a capacitive circuit is said to have a leading power factor indicate, respectively, whether the current is lagging or leading the applied voltage. (Stevenson Jr.)

What is loss factor and how it is used in system's loss analysis? When a loss study is performed on a particular item of equipment, peak load conditions are often assumed in the first analysis. After peak load losses are determined, the cost of these losses is computed using the calculated demand cost of losses . After peak load losses are figured, the total energy dissipated in losses over a year must be determined.

What is load factor used for in power system? Load factor in electrical context is defined as the ratio between the Average Load of the electrical system to the Maximum Demand that it attained. This is factor is used to determine the level of difference between the average load to the peak load. Like the Demand Factor , Load factor is also expressed in percentage form.

What is demand factor and how it serves as a good indicator in eletric utilities? Demand factor in electrical context is defined simply as the ratio of the maximum demand attained and the total connected load . This factor is usually expressed in percent form which represents the level of the existing demand to the available capacity of the system.

How to determine the electric utility's overall power system's loss? Solving for an Electric Utility's Overall system's loss can be easier than you can think of. Distribution Utilities computes their over all Percent System's loss  in a very simple manner. The result of this computation serves as a signal on how the company is doing with respect to minimizing their energy losses and how are they performing.

How to compute for the losses found in transformers? We mention in the previous articles the different types of internel energy dissipation of transformers . Here we will be showing you some basic formulas used in computing for the said losses ;
