power systems loss

ACCR versus ACSR Customer demand for power grows, renewable generators wait for interconnection, and intermittent resources demand more flexibility from aging infrastructure. Yet dense populations, environmental concerns, permitting requirements, and land scarcity intensify the schedule, budget and regulatory risks of building or rebuilding lines. To solve these challenges, 3M developed Aluminum Conductor Composite Reinforced (3M™ CCR). 3M ACCR is an advanced transmission conductor designed to replace ACSR or ACSS on existing structures at the same tensions and clearances, giving you up to twice the capacity without the risks of a major construction project. Your line is in service fast, within budget, and with minimal environmental impacts. And the available trapwire options may help improve the line’s efficiency.

ERC Lowers System Loss Cap BY JORDEENE SHEEX LAGARE ON FEBRUARY 23, 2018 Manila Times The Energy Regulatory Commission (ERC) has reduced system loss charges that distribution utilities (DUs) can pass on to their consumers. In a statement on Wednesday, ERC said that under its Resolution 20, Series of 2017, DUs would have a 6.5-percent distribution loss this year. This would be gradually reduced annually until it reaches 5.5 percent by 2021. Electric cooperatives (ECs), which will be grouped into three clusters based on technical considerations, shall impose a 12-percent cap for 2018. They can charge between 8.25 percent and 12 percent until 2022 onward, depending on which cluster they are assigned to. READ MORE

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.
