TA-300A is a circuit breaker & disconnecting switch tester equipped with a variable power supply. It can record contact operations and current waveforms. One can perform the test safely and efficiently. FEATURES High brightness LCD Simple operations by a touch panel operation Built-in induction voltage elimination circuit ・Get test result completely free from influence of induced voltage. Pre-closing time of the ohmic contact measurement ・Display of measurement results waveform of ‘ohmic contact’ and ‘pre-closing’ time. Automatic pumping prevention check ・Check CB’ s internal fail-safe function. ・Remaining close pulse after CO (trip-free) operation and remove open pulse (trip) and confirm not close CB. Able to perform open-phase test ・Confirm fail-safe function of CB to prevent open-phase situation. ・After open CT’s phase-A and B (or close), test open C (or close) after a few seconds. All test results can be displayed on a screen ・Test result(Numerical value record and Waveform record) can be displayed immediately and easy to confirm evaluation. ・Test result data can be saved up to 50 events and downloaded by using the PC’s browser via LAN I/F. ・Also it is possible to print.
