How transformer calibration test station?
Publishers£ºadmin Published£º2014-12-24 Read£º1634Secondary

Why do we need to change the current on the line it? This is because, depending on power generation and electricity, the current line sizes, and disparities, some only a few safe, but some as large as tens of thousands of security. To directly measure these various currents, it is necessary according to the size of the line current, making the appropriate security until a few tens of thousands of security many different meter and other electrical instruments. This will bring great difficulties to the instrument manufacturer. In addition, some high-voltage lines, such as 220,000 volts or 10,000-volt high-voltage transmission power lines, etc., to directly measure current with high-voltage electric meter on the road, it is extremely dangerous, and it is absolutely not allowed
