power systems loss

Factors/Risks associated with increase in distribution’s systems loss Increase in utility’s system’s kWh loss can be attributed to many factors. We all know that the components of a utility’s systems loss can be from technical loss or from non-technical loss. As a review, technical loss is the inherent properties of electrical equipment and devices during operation while non-technical loss is the result of electricity pilferage, error in meter reading, etc. 

How to detect possible electricity pilferage? We all know that system’s loss is composed primarily of technical loss and non-technical loss. Technical loss is the inherent property of all electrical devices during operation while non-technical losses are caused by electricity theft and/or metering inaccuracies. Technical loss can be determined through computations and the use of measuring devices. On the other hand, non-technical loss cannot be measured nor be computed; instead one has to have various methods just to detect such loss.

Author: Sarang Pande and Prof. Dr. J.G. Ghodekar ABSTRACT: Power system losses can be divided into two categories: technical losses and non-technical losses. Technical losses are naturally occurring losses (caused by actions internal to the power system) and consist mainly of power dissipation in electrical system components such as transmission lines, power transformers, measurement systems, etc. Technical losses result from the impedance of the network components such as electric lines/ cables, transformers, metering and protecting equipment etc. Non-technical losses, on the other hand, are caused by theft, metering inaccuracies. In this paper a method for energy loss calculation is presented.

How to save energy in using inverter technology? An inverter used either in air conditioning or refrigeration basic benefit is its significant energy saving capabilities. Inverter technology allows the air conditioner/refrigerator automatically vary its power output to specifically maintain room temperature at a desired or comfortable level. Basically, the inverter is used to control the speed of the compressor motor to allow continuously regulated temperature. In contrast, a non-inverter appliance maintains the temperature by repeatedly switching power on and off, which consumes much more electrical energy upon starting.

Typical Loss for Amorphous-Metal Core Distribution Transformers. The losses shown in the table are the typical values of a amorphous-metal cored distribution transformers. Core loss and Winding loss (watts) varies relatively as with the increase of the distribution transformer's kVA capacity. Also shown are he respective kilo-watthour loss in annual basis for different transformer capacity in 30% and 40% load factor. Annual kwh are based on peak transformer kW loading equal to kVA size.

Typical Loss for Silicon-Core Distribution Transformers The losses shown in the table are the typical values of silicon-cored distribution transformers. Core loss and Winding loss (watts) varies relatively as with the increase of the distribution transformer's kVA capacity. Also shown are he respective kilo-watthour loss in annual basis for different transformer capacity in 30% and 40% load factor. Annual kwh are based on peak transformer kW loading equal to kVA size.

Typical No-Load loss and Load loss for Power Transformers according to MVA capacity. No-load loss and Load loss in Power Transformers varies significantly depending on different factors. Here you can find the typical value for the no-load loss and load loss according to power transformers having Load Tap changers and those having none. Different MVA capacity means also having different values for the power transformers' no-load and load loss.
