We offer service in the preparation of the Instruction Systems. (Application of ISO standards, important).

For the development of the electricity companies it is necessary to implement a system of instructions that regulate the technical-productive activity on a basis of industrial safety. These instructions are related to each other in a harmonious way, to be able to perform any type of work. 

General industrial safety instructions (INT 1000): list all industrial safety instructions: those associated with physical and psychological attitudes, grounding equipment, safety distances and training; there is no room left for the incongruent elements of the security system.

Instructions on personal security means (INT 2000): are those related to the personal security means of the lineman, the substation operator and the other workers who use them during the working day; for example, work boots, helmet etc. They are the rules of use and their limitations.

Instructions for work on de-energized power lines (INT 3000): they constitute the set of work rules for de-energized activities. They have great importance, since in most of the electrical companies, linemen pass through this type of work at the beginning of their working life; example, they make post changes, build lines, etc.

Instructions for work on energized power lines (INT 4000): they show all the instructions of the work energized in all the voltages; and also, all work procedures appear for different techniques: contact, distance and potential.

Instructions for work on de-energized electrical substations INT 5000: de-energized work in substations must be governed by instructions; which are in correspondence with the activities that are developed in a systematic way; for example, maintenance of ground systems, switches, etc.

Instructions for work in energized substations (INT 6000): substations are the most significant link in the energy chain of a power system; for this reason, it does not make sense to have a great development of the work energized only in the lines, without at the same time having it in the substations. From this, it is deduced that the work energized in the substations is extremely important for the development of a company; Therefore, the need to have instructions in this area is essential.

Instructions for work on de-energized electrical cameras (INT 7000): the work in transformation and interconnection chambers is a very important and decisive part in the operation of buried lines, always these interconnections are of great value for the operation of the electrical system of a city.

Instructions for work on energized electrical cameras (INT 8000): works in transformation chambers are of vital importance in the development of urban electricity, this system is integrated into the distribution of electrical energy; therefore, the instructions to regulate its operation are fundamental.

Instructions for electricity generation systems (INT 9000): with these instructions we relate all generation systems, maintenance, operation of power plants.

Instructions for the use of energized and de-energized working media in power lines, substations and electrical cameras (INT 10000): poles, covers, guards, tension conveyors, etc., as means of work are equipped with the instructions that regulate its use, maintenance and testing.

Instructions on work equipment (INT 11000): the use of work equipment in lines, in substations and in other activities, must also be governed by instructions; which, in an organized way, are part of the quality assurance system of the electric companies.

Instructions for laboratory dielectric tests (INT 12000): it is imperative that all means and tools for de-energized and energized work must be tested in the dielectric testing laboratory; this responds to the purpose of giving security guarantees during its operation; For example, dielectric tests on rubber gloves, blankets, hot stick, etc. are essential.

Instructions for the use of materials and electrical equipment (INT 13000): the materials and the elements that intervene in the electrical system require instructions and technical specifications; which are essential for the use and management of poles, crossheads, reclosers, capacitors, etc.

Instructions for fire protection systems (INT 16000): it is essential for electrical companies to have fire regulations due to the importance of their facilities; The calculations and risk factors of each installation are included in these standards.

Instructions for electrical protections of power systems (INT 17000). electric power systems have to be protected by protection standards; which guarantee the fast, safe and selective disconnection of the failed element (lines, transformers, generators, etc); of these functions will depend the stability of the System, and of course, the damages to said equipment. In the special case of line protection, there is an additional function, which is to locate the point of failure; For this reason, it is important to have all the elements associated with the protections, attacked with procedures and with the instructions of each of the parties involved.
