Earth Resistance Tester Megger Equipment Product Description

HGKG-6 high-voltage switch dynamic characteristics tester is a special instrument developed by our company to meet the needs of on-site testing of high-voltage switch action characteristics. It uses a single-chip microcomputer as the core for sampling, processing and output. The main features of the instrument are that it uses Chinese characters to prompt the operation in a human-computer dialogue mode, and the results are displayed in Chinese characters and printed out. It has the advantages of intelligence, multiple functions, accurate data, strong anti-interference, simple operation, small size, light weight, and beautiful appearance. The high-voltage switch dynamic characteristics tester is suitable for dynamic characteristics testing of various indoor and outdoor switches with little oil, more oil, vacuum switches, and sulfur hexafluoride switches. The portable Transformer Measurement Instruments is a high-performance tool designed for on-site transformer testing, which can quickly and accurately evaluate the performance and health of the transformer.

Features:

Adopting precision bridge measurement technology, the ratio measurement accuracy is as high as ±0.1%.
The equipment is highly portable, suitable for on-site use, and can expand the measurement range.
The frequency response analysis method is used to detect the deformation of the transformer winding.
Applicable to transformers with voltage levels of 6kV and above.
Provide a stable and uniform temperature environment without the need for liquid media.
It is highly portable and suitable for on-site calibration work, and the temperature rises and falls quickly.
High-precision measurement of transformer short-circuit impedance, no-load loss, insulation resistance and other parameters.
Provide comprehensive data analysis and report generation functions.

Application scenarios:

Applicable to on-site testing of substations, power plants and industrial facilities.
Applicable to quality inspection of transformer manufacturers and on-site acceptance of power systems.
Used to evaluate whether the transformer winding is deformed due to short-circuit current or physical impact during operation or transportation.
Supports live or power-off testing, suitable for multiple brands of tap changers.

Operational Highlights:

Insulation resistance tester, also known as megohmmeter, shaker, is an instrument used to measure the insulation resistance of electrical equipment. A hand-cranked generator or an internal DC power supply generates a DC high voltage, which is applied to both ends of the insulation resistance to be tested. According to Ohm's law, the current passing through the insulation resistance is measured, and then the insulation resistance value is calculated.
