The NR-CT series intelligent power frequency withstand voltage test device is a state-of-the-art intelligent withstand voltage test equipment designed according to the latest national power industry standards. It is used to perform insulation strength tests on various electrical products, electrical components, and insulating materials under specified voltages to assess the insulation level of products, identify insulation defects in the tested samples, and measure the ability to withstand overvoltage. It is widely used in electrical manufacturing departments, power operation departments, research institutions, and universities.
◆ Equipped with 5.7-inch and 14-inch LCD displays and a high-speed thermal printer.
◆ Four measurement methods: high-voltage voltage, high-voltage current, low-voltage voltage, and low-voltage current; high-precision sensors and high-performance 14-bit AD acquisition chips.
◆ Full-keyboard operation with human-computer dialogue, intelligent operation throughout the process, selectable automatic and manual modes.
◆ Real-time display of high-voltage voltage, high-voltage current, low-voltage voltage, low-voltage current, time, and withstand voltage results; clear and intuitive display.
◆ Complete overvoltage and overcurrent protection; arbitrary setting of output voltage, high-voltage current upper limit, low-voltage current upper limit, and timing time.
◆ With zero return detection function; the test can only be performed after zero return is confirmed, ensuring safety and reliability.
◆ Approaching voltage regulation algorithm; automatic withstand voltage timing after reaching the set voltage, and automatic voltage reduction and return to zero after timing.
◆ Automatically cuts off voltage output, reduces voltage and returns to zero, and generates an audible and visual alarm when the set high-voltage current or low-voltage current is exceeded.
◆ Excellent software and hardware anti-interference design, multiple anti-interference measures, suitable for harsh electromagnetic environments.
◆ Automatic error diagnosis, easy to identify and solve problems.
