PAPER ON FEEDER RECONFIGURATION FOR LOSS REDUCTION IN THREE PHASE DISTRIBUTION SYSTEM UNDER UNBALANCED LOADING CONDITION

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.

PAPER ON REDUCTION OF POWER LOSSES USING PHASE LOAD BALANCING METHOD IN POWER NETWORKS

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.

SUPERCONDUCTORS FOR POWER TRANSMISSION AND DISTRIBUTION

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?

SUPERCONDUCTORS: LOSSLESS TRANSMISSION OF ELECTRICITY

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.

SAFEGUARDS FOR INSTALLING WIRES AND CABLES

Steps in safeguarding wires and cables when installing it in conduits. Investigations have shown that cable failures often can be attributed to damage caused during installation due to carelessness, inexperience and inability to observe certain simple precautions. In order to eliminate such preventable causes of electrical shutdowns and loss of production, the following procedures should be followed:

THREE-PHASE TRANSFORMER BANKS USING SINGLE-PHASE TRANSFORMERS

Principles in using single-phase transformers to create a three-phase banks. There can be advantages to using single-phase transformers to make a three- phase bank instead of building a three-phase unit. For instance, it may be impossible or impractical to fabricate or ship a three-phase transformer with an extremely large MVA capacity.
