. Technical standards form huge, more less compact systems. Such systems are formed electrical engineering well. Let investigate such systems. The conception safety electrical engineering given basic safety standards. BASIC ELECTROTECHNICAL STANDARDS 2. Technical standards are not obligatory the way legal rules but the fulfillment the requirements technical standard can prevent from many difficulties connected with legal rules. Nowadays, technical products are complicated that technical requirements for one type equipment, device, appliance, installation cannot be comprehended one standard only. is impossible for any standard represent full set technical requirements for the given type of product, equipment, installation. That just the violation law, which can penalized. Most products electrical engineering are used persons. Moreover in case that product complying with the relevant standard causes damage, the position the producer much better than the position that one whose product does not comply with the standard.g. One the basic legal rules prescribed many laws the rule prescribing that nobody shall endanger anybody. Nevertheless, the standard applied for the product cannot prescribe all measures that could should done. The standard respective for given product does not repeat all safety requirements but only refers basic group safety standards. Technical standards are not papers brochures independent one the other. General In the technical sphere, the legal rules obligatory given laws, acts, notices, orders, regulations and directives cannot prescribe the detailed technical performance equipment, installation appliance fulfill the concepts safety, reliability, and maintainability.1. prevent the danger means fulfill respective requirements the respective standard. The rules safety for groups products are given group safety standards. The described rules for the technical performance products (e. the producer keeps relevant standards, can almost sure that his products will not endanger any customer. And manufacturing products assembling equipment that not safe may endanger the purchaser. Present-day technology well present-day equipment and products the field the electrical engineering are complicated that keeping the safety rules very difficult, therefore these rules are comprehended technical standards. machines, appliances, and devices) mounted parts, and for technological procedures are given technical standards.BASIC ELECTROTECHNICAL STANDARDS 12 2.
