Electric Power Engineering Research Laboratory (EPERL) was established in April 2004 as one of eight new laboratories according to the restructuring of Central Research Institute of Electric Power Industry (CRIEPI) organization in order to contribute to society through development of new technology. EPERL is situated on the Yokosuka site on the west coast (Sagami Bay) of the Miura peninsula in Kanagawa prefecture.
Main missions of EPERL are development of lifetime estimation methods for aged power apparatus and cables in transmission and distribution systems, development of insulation design and lightning protection methods for power apparatus, solution of electromagnetic compatibility (EMC) and electromagnetic field (EMF) issues, development of appropriate countermeasures for high-current arc, development of next-generation power technologies, and realization of laser, plasma, and superconductivity applications.
This research sector aims to develop lifetime evaluation and diagnostic methods for power apparatus and cables for transmission and distribution systems, and to propose next-generation gas insulated switch gear and all-solid insulated substations.
This research sector aims to develop insulation design and lightning protection methods for electric power and telecommunication systems, and to solve EMC and EMF issues.
This research sector aims to realize laser and plasma applications to enhance the performance of power transmission equipment and materials, and to ascertain their durability against large-fault current and high power arc.
This research sector aims to realize power electronics and superconductivity applications to enhance the performance of power transmission equipment, and to develop electromagnetic transient analysis methods for power systems.
This laboratory belongs to the EPERL and has been internationally certified by JAB (The Japan Accreditation Board for Conformity Assessment) as an independent organization. This laboratory can issue certification for the durability of power equipment and materials.
Shiobara testing yard was constructed at Shiobara, Tochigi pref. in 1961 to obtain the data necessary to design 500kV class AC transmission lines. Now, this testing yard is used for experimental research on protecting power transmission lines, distribution lines, and ICT equipment from lightning.
