What is the working principle of digital insulation resistance tester?
The working principle of digital insulation resistance tester:Digital insulation resistance tester consists of medium and large scale integrated circuit. The output power of this table is large, the short-circuit current value is high, the output voltage level is many (each model has four voltage levels). The working principle of the machine by high voltage DC battery as a power source via the DC/DC transform generated by E the tested product reaches L, thus generating a current from E to L, after I/V transform directly to complete the operation by division of insulation resistance measured values are displayed by LCD.
BY2671 digital insulation resistance tester is used to measure the insulation resistance of transformers, motors, cables, reactors, generators and other equipment and components. The use of a dedicated high-voltage test line, eliminating the test line on the test results, voltage, multi stall output, easy to use, digital LCD display, reading more intuitive.This instrument does not need manpower to do work, the battery power supply, the range can be automatically converted. The panel operation and LCD display at a glance make the measurement very convenient and fast.The short circuit current output can be measured directly and no load measurement is necessary.
Range of useThis instrument is a common and necessary instrument for power, post and telecommunications, electrical and mechanical installation and maintenance, as well as industrial enterprises that use electricity as industrial power or energy. The utility model is suitable for measuring the resistance value of various insulating materials, and the insulation resistance of transformers, motors, cables, electrical equipment, etc..
