Characteristics of power frequency withstand voltage tester

The power frequency withstand voltage tester is an intelligent withstand voltage test equipment with advanced performance designed according to the national power industry standards. It is safe, reliable, powerful, easy to use and simple to maintain. It is used to conduct insulation strength tests on various electrical products, electrical components, insulating materials, etc. under specified voltages to assess the insulation level of the product, find insulation defects in the tested product, and measure the overvoltage capability.

characteristic

● All-weather large LCD

4.7-foot ultra-large LCD display, clear and intuitive readings (visible in sunlight), high-speed thermal printer, test results can be viewed and printed.

● Digital calibration method

Fully digital calibration method, abandoning the outdated potentiometer adjustment, extremely convenient for on-site use, and easy to control accuracy (this function is password protected)

● The whole test process is displayed on the same screen

High and low voltage, current four-way measurement mode, can monitor high and low voltage current and voltage values ​​in real time. The same screen is divided into voltage and current dynamic display area, setting data area, status information display area, and result display area, so that the test process is clear at a glance. ● High-speed acquisition signal

Adopting high-precision sensors and high-performance 14-bit AD acquisition chips, it can automatically capture peak voltage and current, making it easier to do breakdown tests.

● Intelligent operation of the entire process

You can choose automatic or manual operation, AC/DC withstand voltage mode or cascade withstand voltage mode, and set the output voltage, high and low voltage current upper limit and timing time arbitrarily.

● System diagnostic analysis function

The system has the function of automatic diagnosis and analysis of withstand voltage test, which can easily detect breakdown, flashover and other faults of the test product and help solve the problems.

● Comprehensive protection function

Perfect over-voltage and over-current protection, set value upper limit protection. Approximate voltage regulation algorithm, automatic timing after reaching the set voltage, automatic voltage reduction back to zero after timing. Add "emergency stop" in a conspicuous position, and the power can be cut off at any time during the test.

● System help function interface

After entering the function interface, you can select interfaces such as " Clock Settings", "Precautions", and "Wiring Diagram". You can set the clock time to provide a time basis for printing reports; provide users with some operating specifications and safety precautions; and facilitate users to correctly connect according to the wiring diagram.

● Double over-current protection, safer testing

When the current exceeds the set high or low voltage, the voltage output will be automatically cut off, the voltage will be reduced to zero, and an audible and visual alarm will be issued.

● Safety zero position detection

It has a zero return detection function. The next step can be performed only after the zero return is confirmed. It is safe and reliable.

● Applicable to partial discharge test

It can be used in conjunction with a non-PD test transformer as the operating part of a PD system, with a system PD of less than 5pc.

● Insulation impedance detection function

It has the function of insulation impedance detection, which can directly reflect the insulation strength of the tested product.

● Strong adaptability

Sophisticated software and hardware anti-interference design, multiple anti-interference measures, adaptable to harsh electromagnetic environment.

● Powerful expansion function

The grounding detection function is optional. The voltage can only be increased after ensuring safe grounding before the test begins.

Interfaces such as door interlocks, warning lights, alarms, etc. can be reserved to meet the needs of different customers.

Optional remote communication, external voltage divider calibration interface, etc.

You can choose to preset no less than two voltages and time points. The system can automatically increase or decrease the voltage and maintain the time according to the preset voltage.

● Test result sound alarm function

The test result sound alarm function, when the test passes or fails, the equipment will emit different alarm sounds, and the test personnel can directly identify the test results by the alarm sound
