Computer Aided Harmonic Analysis:

It is required that currency and voltage should be in sinusoidal form and 50 Hz frequency to produce, transmit and distribution of electrical energy. That condition is the main factor in deciding the quality. Due to many reasons, those values lose basic specifications and undesired harmonics appear.

In this paper, the resources of harmonics, its effect on electrical networks are handled and suggestions are given to prevent the harmonics.

Private Sector Energy Investments and Public Loss

Errors in the reports are criticised to investigate the corruption claims in the energy business are discussed in this article, which is prepared by some public institutions to audit the public sector.

Environment Management System (ISO 14001) and the function of environment in relations with the EU

The definitions of “environment” and “sustainable development” are given in this text. And also information is provided on ISO 14001 standards, Turkey’s compliance with the environment standards of the EU.

Notes from the history of electricity

Summaries are passed from the earliest issues of our magazine in this section. And the mentioned topics are commented on from the today’s viewpoint.

For example, a paper headlined as “The Future Phone” (issue: Oct. 1982) handles the expectations on future phones. According to this paper, all expectations on the phones are fully realized and even surpassed technologically.

On the other hand due to insufficient quality of electrical energy, houses with TV receivers had to use regulators in Turkey in 1980s. That caused great loss on both end-users and national economy. Electrical energy consumed by those regulators were higher than produced by The Keban Dam.
