CONTROLLING METHOD OF WITHSTAND VOLTAGE TEST OF EXTRA-HIGH-TENSION UNDERGROUND CABLE FOR POWER TRANSMISSION

摘要

PURPOSE: To save energy for a withstand voltage test of an extra-high-tension cable and to enable continuous execution of a quick, highly precise and stable control. ;CONSTITUTION: Control devices 12A and 12B equipped with digital processing devices are disposed at transmission and reception ends of an extra-high-tension cable 2 respectively. Information needed for a withstand voltage test is collected automatically, the collected information is transmitted mutually through a transmission line 3 and monitoring and control of the test are made executable continuously. Thereby it is made possible to save energy and to execute a highly-precise and stable control.;COPYRIGHT: (C)1996,JPO
