Telecom power supplies and power quality

Proceedings of INTELEC 95. 17th International Telecommunications Energy Conference, 2002
In this paper we address the issue of power quality in relation to the telecommunication power supply. After a general discussion of power quality and related global trends, we present a comprehensive list of line disturbances and investigate the effect of rectifier loads.

Electric power quality and efficiency of power supply

21st IEEE Convention of the Electrical and Electronic Engineers in Israel. Proceedings (Cat. No.00EX377), 2002
The quality of power supply depends on the quality of electrical energy, and also on the frequency and duration of probable interruptions in power supply, which increase with decrease of electric power quality (EPQ). The problem of EPQ has an important economic and technical significance for all countries, including Israel.

Power quality and the security of electricity supply

Proceedings of the IEEE, 2001
The high-tech and knowledge-oriented businesses of the 21st Century require high quality and ultra-reliable power in the quantities and time-frames which have not been experienced before. For mission-critical information systems, the availability of enhanced electric power is a far more important consideration than the commodity cost of electricity ...

Digital control technologies for improving the power quality of power supplies

Neural Computing and Applications, 2012
The power supply designs are becoming digital in nature due to its several advantages. It is common to see what would have once been a completely analog design, now incorporate some combination of DSP, microcontroller, and FPGA technologies. The current harmonics are measured in power supply of color television.

Tools for supplying premium quality power

IEEE Technical Applications Conference and Workshops. Northcon/95. Conference Record, 2002
The electric utility industry has done a good job of minimizing the long term outage, but for some industries, reliable power is not good enough. There is an increasing demand for premium quality power. The proliferation of sensitive electronic equipment at industrial and commercial sites has resulted in an increasing number of major power users who ...

Quality enhances reliability [power supplies]

IEEE Spectrum, 1996
As deregulation dawns, electric utilities are awakening to the fact that power quality counts with many a customer-and counts for a lot. Even now, the groundwork is being laid worldwide for a new type of service contract between a utility and its large industrial or commercial clients.

Sustainable building for the quality of power supply

2005 IEEE Russia Power Tech, 2005
The photovoltaic (PV) systems, together with energy storage devices, interconnected in parallel with the utility can improve the reliability during power quality perturbations in the main system supply. The paper presents a possible solution with high level of power supply continuity, where a hybrid system is simulated in case of power quality negative

Power quality monitoring at the supply side

2001 IEEE/PES Transmission and Distribution Conference and Exposition. Developing New Perspectives (Cat. No.01CH37294), 2002
/sup T/his paper summarizes a power quality (PQ) monitoring investigation conducted at the utility distribution substation level. The main goal was to determine the real-time PQ monitoring issues from the user's perspective: what type of data needs to be captured; and how it should be presented to the user.

Power and relationship quality in supply chains

Asia Pacific Journal of Marketing and Logistics, 2017
PurposeThe purpose of this paper is to test the impact of power (coercive and non-coercive) on supply chain (SC) relationship success. In particular, this paper aims to examine the moderating effect of relationship quality (RQ) on the associations between power bases and relationship success.
