Research Abstract |
As scheduled IEC 61083-2 (Instruments and software used for measurement in high-voltage and high-current test- Requirement for software for tests with impulse voltages and currents) was issued on March 2013 and appendant TDG (Test Data Generator) was also supplied. As the results of this research, a calibrator, which is capable of generating a tail-oscillating impulse voltage waveform referred as OLI-M3 in TDG, was successfully completed. The generation is possible even when its output is connected to a low impedance (10kOhm) potential divider. By using MOS-FET instead of wetted mercury rely as a switching element of the calibrator, deterioration of the contact can be avoided. Massive parallel connection of MOS-FET makes it possible to reduce the non-linear resistive characteristics between source and drain to a negligibly small level. Also, inherent characteristics of MOS-FET in allowable current from source to drain was solved by that parallel connection.
