DEVELOPMENT OF PHASE ANGLE MEASURING DEVICE FOR THYRISTOR CONTROLLED ELECTRIC RAILCAR

In order to comprehend the operational control characteristic of a thyristor phase controlled railcar, it is necessary to measure the controlled phase angle. To make consecutive measuring of controlled phase angle, a method to detect the controlled phase angle by taking the gate signal for measurement and AC power source for synchronization from an electric car was proposed and a trial device was designed and built. As for operational state and characteristic of each circuit of the device, improvements in accuracy and stability were achieved through laboratory and field tests. After feasibility had been confirmed through service tests, a report summarizing the structure, circuits and handling of the device and the test results was written.
