NA23 Type Impulse Peak-Voltmeter
Also name
NA23 impact peak voltage table, the impact pulse peak voltmeter, the impact of the peak ammeter, the impact of the peak table, the peak pulse voltage meter, pulse peak ammeter
Introduce of NA23
NA23 Impact Peak Voltmeter for measuring and storing impulse voltage peaks, peak impulse currents, and other single pulse peaks. An internal calculation unit allows the peak of the voltage divider to be displayed directly in units of kV. Display range from 0.1kV to 16000kV.
The tester designed for use with high pressure laboratories. Use of special wiring, shielding, filtering and over-voltage protection circuit to a high degree of attenuation of electromagnetic interference.
Measuring range
The measuring cable is connected to a low voltage arm or a high current shunt of an impulse voltage divider (resistive or capacitive type device). For measuring the voltage divider (shunt), the impulse peak voltmeter will introduce a load of 2MΩ // 39pf. If necessary, for example, in the case of a resistive shock divider, a 75Ω (or 50Ω) matching resistor can be added to one of the two inputs of the table. The maximum permissible pulse voltage of the device is 1600V. Measured values ??are displayed directly in 5 digits, in kV.
The device is different from the current commonly used impact peak table is characterized by: measuring voltage range without manual switching, and by the device automatically switch. Positive and negative polarity is automatically displayed on the display.
