Load Modelling for a Federal Medical Center in Nigeria under Erratic Power Supply

Childhood mortality in federal medical centre umuahia, South eastern Nigeria.

OBJECTIVES This study aimed to evaluate the mortality pattern in children seen at Federal Medical Centre Umuahia (FMCU) Abia state, South Eastern Nigeria. METHODS A retrospective cross sectional descriptive study over a 5-year period from January 1, 2004 to December 31, 2008 using data retrieved from the hospital's medical records department. RESULTS A total of 3,814 children were admitted ...

Testing a power supply for line and load transients

Line and load transients are step functions that inject disturbances into the power supply. A load transient injects disturbance into the output by stepping the load current, and a line transient does so by stepping the line voltage. The supply’s output response demonstrates its ability to attenuate the various frequency components of a line or load step. The following discussion describes thes...

Wireless Load Self-Disconnection Module For Automatic Power Supply System

Nowadays, the use of Auxiliary power supply (APS) systems to energize low power rating appliances (e.g. televisions, water dispensers, etc.) and lighting (e.g. CFL lamps) has become pervasive in countries where long power rationing schemes are applied. Although the existing APS systems offer overload protection, it cannot be directly connected to the existing electric circuit unless heavy loads...

Load Tap Changing Controls as a Power System Nerve Center

Products based on digital technology for the control of LTC transformers and step-voltage regulators are now entering an evolutionary second generation. Ever more sophisticated concepts are being made available as electronic components become available to accommodate the needs in a cost effective manner. Most notably, this provides a realistic opportunity to use the LTC control as a monitor poi...
