NON-CONTACTING TYPE VOLTAMETER

摘要

A contactless voltameter is provided to prevent a fire caused by electric resistance applied to a connection terminal and excessive current consumed by the connection terminal by removing the connection terminal and an electricity wire from a case. A simulation digital chip(9) and a microprocessor(11) are connected to each other. The microprocessor is connected to a display screen and a communication chip(12) respectively. A board is mounted with a pulse line and a power line, wherein the power line is connected to the digital chip and a power switch(10), and the pulse line is connected to the communication chip. A protecting cover is mounted to the board and a mutual inductor is mounted in the cover.
