How billing timing difference affects systems loss data? Billing timing differences can have an impact on power system loss data, especially if the data is being used for analysis or performance monitoring purposes. This is because billing data is typically collected at different times than system loss data, and these differences can affect the accuracy and reliability of the data. One potential issue is that billing data is often collected on a monthly or quarterly basis, whereas system loss data may be recorded at a higher frequency, such as every 15 minutes or hourly. This means that the billing data may not accurately reflect changes in power consumption or losses that occur on a more granular time scale. Another potential issue is that billing data is usually based on customer meter readings, which are affected by a range of factors, such as meter accuracy, measurement errors, and tampering. This can result in inaccuracies in the billing data, which can in turn affect the accuracy...

Authored by: N. Rugthaicharoencheep and S. Sirisumrannukul Unbalanced loading in electrical networks creates higher losses compared to balanced lines having the same loads. Reconfiguring the set up of the loads reduces the line losses not only to its phase conductors but also to the neutral wire for four-wire system.

Authored by: Dickson K. Chembe, Member, IAENG   Power loss reduction through load balancing serves as an effective and efficient way of reducing loss in power networks. Also, among all the methods identified in reducing power loss this can be considered as the cheapest since this method only requires proper planning and strategy.

How can superconductors be applied in the electric distribution industry? We have defined that superconductors are materials that have no resistance to the flow of electricity and are one of the last great frontiers of scientific discovery.  Having no resistance means having no power loss. So how can we use this technology for industry’s benefits?

What are superconductor’s roles for lossless power distribution? All the power losses that occurs in an electrical system boils down to the fact that all of the components needed to transmit electrical power has resistance. Power losses is dissipated in the form of heat in the electrical system happens because there is an opposition to the flow of current called resistance.

AMR System for electric utility use in automated meter reading AMR system or the Automated Meter Reading System is a modern technology application of automatically collecting information, status report, and reading from utility meters like in the water, gas and energy. This automation process is made possible through the use of digital communication techniques such that it saves utility providers the expense of periodic trips to each physical location to read a meter.

Reducing electric power loss using the demand side of the utility Reducing losses in an electric utility can be done in many different ways each of its own advantages and disadvantages. Majority of this loss reduction program focuses on the supply side of the utility. To name a few includes conductor wire upgrades, increasing the primary voltages, balancing the currents in each phases, adding line capacitors and many more.

Which is better for voltage regulation, capacitor ot voltage regulator? One of the greatest advantages gained by the proper sizing and location of distribution capacitors is voltage improvement. By placing leading volt-amperes reactive (VAR) loads (capacitors) near lagging VAR load centers (motors for example), the lagging VARs on a system basis are cancelled with an associated increase in voltage.

What is the difference between substation capacitor and line capacitors? If capacitors are installed primarily to reduce or eliminate bulk power charges for kVAR or for other reasons associated with wholesale purchased power such as contractual requirements, they can be installed in substations to supplement distribution line installations. Installed equipment cost for substation capacitors may be less than that for the same amount of line kVAR because the substation units can package many kVAR in a single installation and can be switched with a single three-phase switching device and control unit. However, the distributor does not get the benefit of reduced distribution line losses by installing capacitors at substations, so such installations should be made only after the maximum practical amount of line capacitors has been installed.

How to minimize loss on Voltage Regulators Operation? To minimize losses on substation regulators , either separate units or substaton load tap changers, the high-voltage tap setting on the substation transformer should be set so the regulators will spend the maximum amount of time near the neutral position, since regulator losses increase as the regulator tap position farther away from neutral. Ideally substation regulators should spend approximately the same amount of time bucking voltage as they do boosting voltage. This keeps the regulators near neutral under average system conditions.

A technical paper completed by Juan Carlos Olivares, Member, IEEE, Yilu Liu, Senior Member, IEEE, Jose M. Cañedo, Member, IEEE,Rafael Escarela-Pérez, Member, IEEE, Johan Driesen, Member, IEEE, and Pablo Moreno, Member, IEEE ABSTRACT This paper examines three methods of reducing distribution transformer losses . The first method analyzes the effects of using aluminum electromagnetic shields in a distribution transformer. The goal of placing electromagnetic shields in the distribution-transformer tank walls is to reduce the stray losses. A 500-kVA shell-type transformer was used in the experiments.

How line reconductoring affects distribution line loss? Our basics in electrical study from the past taught us the relationship between conductor resistance and conductor size. We’ve learned that conductor resistance is inversely proportional to the cross-sectional area of the conductor and directly proportional to its length. This means that for a given same type of material, when the conductor’s cross-sectional area increases, its resistance will decrease proportionally. While if the conductor length increases, its total line resistance will also increase proportionally.

How phase load balancing affects losses in the distribution lines? The most efficient way for a three-phase line or even a V-phase system to operate is when the loading on each line is said to be balanced. As what we constantly say, distribution line loss is dependent mainly to the two main variables, the line resistance and the line current.

  How single-phase to three-phase conversion affects distribution line losses? Electric Utilities around the world typically uses three-phase system in distributing power. Three-phase system is said to be relatively more superior compared to using a single-phase . The idea of a three-phase power was first conceived by non other than the founder of Alternating Current electricity, Nikola Tesla .

What are the actions taken in reducing line loss in distribution system? The key in minimizing the over-all line loss in any distribution system is through current reduction. In computing for the line loss of a distribution feeder we basically use the I^2R formula. The function of current in this formula is in the exponential form. Because of this , a small change in current would be exponentially felt in the power loss of the feeder. Any effort to reduce the line current is also an effort in loss reduction.

  What are the effects of converting the operating voltage of distribution system? In distribution system loss reduction , it has been known that one option of minimizing the losses produced in the distribution system is through voltage conversion. An example would be if a utility has an operating voltage of 13.8kV and they want to reduce their line loss, converting it to 23kV would be an effective move. However, this action can not simply be done without affecting anything especially when considering the economic factors.

Generally, two main types of losses exist during an electrical power transformation and are also inherent in every transformer. We have the load loss also known as the winding loss where this type of loss depends on the loading of the transformer, the higher the load, the higher the loss that it can generate. Also, we have the no-load loss also known as the core loss where this is type of loss is constant in every transformer regardless it is fully loaded or no-load at all.
