Connectors, which are components for connecting different types of conductors to each other and to other equipment in the power grid, are installed in large numbers in the medium and low voltage distribution network. Use of the general and international standards in the development of national standards related to these parts, without completing and developing specialized/supplementary guidelines for the characteristics of these parts that are less discussed in the general standards, leads to numerous problems, including spending a lot of time and money to repair and replacement of these parts, unwanted power outages and also high electric power losses. The present paper shows that such an approach in the development of national standards, while causing defects in more than 100,000 of these components each year, has led to relatively high power losses due to the presence of these components in the medium voltage distribution network. By developing optimal standards based on the technical/economic conditions of the country, the problems related to these parts can be greatly reduced. It is suggested that a technical committee be set up in the relevant national commissions to analyze the problems, provide solutions and develop optimal standards.
