Since 1963, the Electric Power Engineering Research Laboratory of theCRIEPI has conducted research andtests on the short-circuit performance ofpower equipment and materials at its
high-power test facilities, as well as at its
previous organization, the High Voltage
Power Laboratory.
When a short-circuit fault occurs in
power systems, high current several todozens of times as normal current flows
to the fault point and power equipment
may be damaged. Therefore, short-circuit testing is important to build safe
power equipment. The research results
are used to develop higher-performancepower equipment that can withstandhigh currents, and eliminate fault
currents quickly. We are currently developing an appropriate test method and ahighly precise measuring technique forshort-circuit performance evaluation.
The High Power Testing Laboratory
was established in April 2001, and laboratory accreditation was granted by theJapan Accreditation Board for Conformity Assessment (JAB) in compliance withISO/IEC 17025. As a laboratory thatmeets international standards, we areinvolved in a variety of test activities that
include publishing test reports and issuing certificates.
