HZ5375 5000A Primary Current Injection Test Equipment

Specifications

Working principle

(1). The measuring circuit of the instrument includes a current measuring circuit and a current measuring circuit. (Voltage test can be added as required) The volt ampere characteristic function can be expanded.

(2). The current measuring circuit includes micro current zero impedance CT, programmable amplifier circuit and sampling circuit.

(3). The voltage measurement circuit includes PT isolated signal acquisition circuit, programmable amplifier circuit and sampling circuit.

(4). The 16 bit single-chip microcomputer uses the computer digital real-time acquisition method to calculate the high-voltage voltage measurement value by measuring the amplitude of the voltage signal according to the voltage proportional relationship. The automatic timing function is realized by comparing the measured voltage signal amplitude with the set voltage value. The current output of the device can be calculated according to the current proportional relationship, The over-current protection function is realized by measuring the amplitude of current/voltage signal and comparing it with the set value.
