| Abstract: | A new method calibrating direct current resistance measurer with active high power direct current standard resistor box is introduced which consists of a high-power standard resistor and a precise electronic voltage transformer box. The influence of big current and high power in calibration is avoided in this method. The high power direct current standard resistor box is introduced in detail in hardware and software design with analyzing its source of error. The experimental results indicate that this method is easy to operate and the result is precise. It has the capability to replace the traditional method which adopts high-power standard resistors. |
