Automatizované testování imunity střídavého relé

Abstract

The goal of the bachelor thesis is to design and realization hardware and software for automated testing of immunity relay with 24 V AC supply power. The program is created in LabVIEW 2012. This program will automatically testing AC relay and it’s immunity to short interruptions of supply voltage drop at an angle of 0 to 180°. For setting (change) power signal and measuring switching supply voltage is used measuring card. For amplify the output signal from measuring car is used low-frekvency amplifier, which has outputs there is required power signal. Other parts of low-frekvency amplifier there are supply circuit with transformer.
