METHOD AND DEVICE FOR MEASURING GROUNDING SYSTEM NOISE PROPAGATION CHARACTERISTIC IN NUCLEAR POWER PLANT

摘要

PPROBLEM TO BE SOLVED: To measure electric characteristics between separated grounding points. PSOLUTION: This device is equipped with: a network analyzer for measuring an electric characteristic between grounding points; a coaxial cable for measurement for connecting each middle point between a sensor, a preamplifier, a motor and an inverter, and each grounding point to the network analyzer; and a short-circuit cable for short-circuiting a shield of each coaxial cable for measurement. Thus, the electric characteristics between separated grounding points can measure. PCOPYRIGHT: (C)2011,JPO&INPIT
