Technical Specifications
Its scale unit is megohm, which has a high voltage power supply. Loop; The third is display. A special instrument used to measure the maximum resistance, insulation resistance, absorption ratio and polarization index. Its scale unit is megohm, which has a high voltage power supply. Insulation resistance meter, also known as megameter, table, and Meg, the insulation resistance meter is mainly composed of three parts; The first is the dc high voltage generator to produce the dc high voltage; The second is to measure the special instrument used to measure the maximum resistance, insulation resistance, absorption ratio and polarization index.
Structure and Composition:
DC high voltage generator.
The high voltage value is specified in the national standard of insulation resistance as 50V, 100V, 250V, 500V, 1000V, 2500V, 5000V. The measuring insulation resistance must be applied at the measuring end of a high voltage.
The second one is through the pressure of the municipal transformer, the rectifier gets the dc high voltage. The method used in general electric megohm meter. There are generally three methods for generating dc high voltage. The first type of hand generator. At present, about 80% of the megol meter produced in China is used in this way (table name source). The third is the use of transistor oscillating or special pulse width modulation circuit to produce dc high voltage, general battery type and municipal electrical insulation resistance meter.
