MIVLF-Z ultra-low frequency high voltage generator

MIVLF-Z ultra-low frequency high voltage generator

Product Introduction

Application of ultra-low frequency high voltage generator
MIVLF-30KV 40KV 50KV 60KV 80KV/0.1HzThe ultra-low frequency high voltage generator is suitable for the withstand voltage test of cross-linked polyethylene insulated power cables/Voltage withstand test for hydroelectric generators and large generators.0.1HzThe ultra-low frequency insulation withstand voltage test is actually an alternative method to the power frequency withstand voltage test. Especially when conducting power frequency withstand voltage tests on large generators, cables, and other test samples, it plays a significant role.
0.1HzThe ultra-low frequency high voltage generator complies with the following power industry standards:
Execution standard:DL/T 849.4-2004《35kVCross linked polyethylene insulated power cables with ultra-low frequency and below（0.1Hz）Industry standard for voltage withstand test method, General technical specifications for specialized testing instruments for power equipment, Section4Part: General Technical Conditions for Ultra Low Frequency High Voltage Generators

There are many commonly used aliases for ultra-low frequency high-voltage generators in the industry, such as ultra-low frequency withstand voltage tester and ultra-low frequency withstand voltage testing device. Although the names are different, they are actually all ultra-low frequency high-voltage generators, or devices with ultra-low frequency high-voltage generators as the core equipment, combined with other components, for high-voltage withstand voltage testing.
MIVLF-Z ultra-low frequency high voltage generatorCombining modern digital frequency conversion technology, adopting microcomputer control, boosting, lowering, measuring, and protecting automation, and capable of manual intervention during the automatic boosting process. Due to full electronicization, it has a small size, light weight, large screen LCD display, clear and intuitive display, and can display output waveforms and printer output test reports. The design indicators comply with the General Technical Conditions for Special Testing Instruments for Power Equipment, Section4Part: General Technical Conditions for Ultra Low Frequency High Voltage Generators "is a standard in the power industry, which is very convenient to use. Nowadays, both domestically and internationally, mechanical methods are used for modulation and demodulation to generate ultra-low frequency signals, resulting in non-standard sine wave waveforms, large measurement errors, spark discharge in the high-voltage part, bulky equipment, and high-power high-voltage resistors for discharge shaping in the second and fourth quadrants of the sine wave. Therefore, the overall power consumption of the equipment is relatively high. This product can overcome these shortcomings.

Product features

1The current, voltage, and waveform data are all directly obtained through high-voltage side sampling, so the data is true and accurate
2Overvoltage protection: When the output exceeds the set voltage limit, the instrument will shut down for protection, with an action time of less than 20 milliseconds
3Overcurrent protection: designed as a dual protection of high and low voltage, the high voltage side can be precisely shut down for protection according to the set value
4When the current on the low-voltage side exceeds the rated current, a shutdown protection will be implemented, with an action time of less than 20 milliseconds
5The high-voltage output protection resistor is designed inside the boost body, so there is no need to connect another protection resistor externally
6Due to the use of high and low voltage closed-loop negative feedback control circuit, there is no capacitance rise effect in the output
