CESEMET Project: Power quality monitoring equipment

CESEMET Project: Power quality monitoring equipment

Project director: Eng. Cornelia Bodirnea (ICMET Craiova)

The main objective is to identify connections in an interdisciplinary field. These make it possible to take over cutting-edge technological achievements. We draw inspiration directly from other modern sectors of technology. We want to increase the technical level of electrotechnical equipment. We aim to increase efficiency and reduce global energy consumption. Environmental conservation is another essential aspect targeted.

The purpose of the project is to accurately monitor energy quality. We are particularly targeting medium voltage power grids. We aim to obtain energy that is as clean and safe as possible. The project is highly topical and important. Energy quality depends on both the producer and the consumer.

Consumers can significantly disrupt the power factor in the network. The project proposes to replace classic current measuring transformers. We will use unconventional sensors incorporated in insulating bushings. This innovative solution is applied to medium voltage equipment.

Applied research directions

• We carry out complex and detailed applied research;
• We are creating a functional model that will be practically tested;
• We are introducing the new model directly into the national electricity system;
• We ensure the dissemination of information in recognized specialized journals;
• We actively participate in conferences and organize thematic symposia.

Long-term strategic objectives

• We create a modern technological network for insulating passages;
• We manufacture components with modern silicone rubber insulators;
• We include current measurement systems with unconventional sensors;
• We attract and train young graduates in research activities;
• We publish articles and books to prepare for future partnerships;
• We are developing the results towards the creation of a fully approved prototype.

The project topic is part of a strategic area at national and European level. We directly target clean energy and rigorous monitoring of networks. This monitoring allows immediate measures to be taken to improve the power factor. By applying the results, we obtain direct benefits at medium voltage. Our equipment offers high-quality components and high precision. The modern measurement principle guarantees these competitive advantages.

We have obvious economic components due to the much reduced technical dimensions. This results in a visibly reduced consumption of materials. The sensors are incorporated directly into the medium voltage insulating bushings. The materials used, such as silicone rubber, are much more economical. These technological upgrades of the insulators naturally impose themselves on the market. The equipment becomes much more cost-effective through integrated current measurement.

From the point of view of exploitation, the project protects the environment excellently. The health of the service personnel in the stations is much better ensured. The new models are clearly superior to the classic ceramic insulators. We specify that the new insulating bushings together with the composite insulators are extremely reliable. They have a significantly longer lifespan.

In addition, we strictly address the requirements of electromagnetic compatibility of the network. Non-conventional sensors ensure the elimination or reduction of disturbing electromagnetic fields. The influence of the fields is effectively maintained within the strict permitted limits. This prevents dangerous exposure of personnel in power stations.
