High-voltage laboratory complexes are one of the most essential equipment of research, industrial and high-level research institutes working in the field of high voltage for understanding the principle governing the physics of high voltage such as the occurrence of electrical drainage in insulated environment (air, gas, liquid and solid) and helping the study of the performance of electrical equipment under high voltage direct, alternating, and shock waves.
In order to apply high-voltage engineering science in the advanced industrial countries, today many steps have been taken and significant achievements have been achieved. JDEVS felt this gap in field and decided to starts working professionally since 1986 considering its scientific capabilities and experienced personnel.Research began in this field and, with the help of God, after seven years of implementing various research projects in the laboratory and semi-industrial stages, the ـJDEVS high-voltage engineering center ـsucceeded in building high-voltage laboratory complexes up to 400 kW-voltage voltages.
Research activities in the field of high-voltage equipment continued with the use of the existing knowledge and experience of the experts. Todays, after 25 years of continuous research and production, it is possible to produce high-voltage sets including AC, DC and Impulse generators up to several milliliters of voltages according to the international standards and more than 140 manufacturing units and training centers are operating at high-voltage engineering center.
Achieving the technology for the production of high-voltage components and generators has madeJDEVS as one of the most prestigious technical and engineering complexes in the field of high-voltage engineering in the country and as a reference point in the control of the quality of electrical equipment in the electric power industry of Iran to provide valuable services to various industries in the country.
In order to confirm this issue, the third rank of user research of the 12th Kharazmi International Festival as well as the registration of the JDEVS Laboratory Equipment Complex at the Office of Inventions and Innovations of Tavanir Power Industry.
The objectives of the engineering center are based on the following criteria:
AC test systems consist of modular transformer units that can be cascaded up to three stages to get higher voltages ranging up to 1200 kV. Our AC test systems can be provided with low or high power ratings. Small AC test systems with low power are mainly suitable for performing dielectric tests, whereas large systems with high power can be used to carry out additional tests such as high voltage withstand tests.

This center has so far been able to carry out valuable expertise and professional test services for industries and manufacturers which use high voltage equipment, as well as making high voltage test laboratory for higher education institutions and universities according to international standards. This center also has higher voltage test laboratory and portable high voltage equipment for proposing type and routine test services at its own laboratory and on-site test.
Based on our experience and well-equipped facilities, we offer a wide range of quality control services and onsite testing to our clients according to well-known standards
Impulse test systems are based on the Marx generator. They provide the standard lightning (1.2 µs / 50 µs) and switching (250 µs / 2500 µs) impulses to test various test objects such as transformers, bushings, cables, insulators, switchgears, and many more from 10 kV upto 2.4 MV other specifications upon request.
The modular test system is based on portable and light elements which can constitute suitable circuits to provide AC, DC, and impulse voltages. For example a DC test system is based on an AC voltage transformer which charges HV capacitors with a DC voltage through HV diodes and resistors. These systems provide high DC voltages to test HVDC facilities, long AC cables, capacitors and so on
