GDZRS-20A Three Phase DC Winding Resistance Tester
This DC resistance quick tester (hereinafter referred to as the DC winding resistance tester) is the latest generation product for measuring the DC resistance of transformers. It is optimized for measuring the DC resistance of three-phase windings of large-capacity transformers. The DC resistance of the three-phase windings of the transformer can be tested simultaneously. For the on-load voltage regulating transformer, it is not necessary to discharge the tap changer directly, and the measurement time is one third of the traditional single-phase measurement, which can greatly shorten the working time and labor intensity. The direct resistance meter adopts a large-screen liquid crystal display, all Chinese graphical interface, clear and intuitive, and the operation is very simple. And equipped with panel printer and large-capacity non-volatile memory, you can easily store and print the measurement results. The test data is stable, fast and repeatable, and it is the best choice for measuring the DC resistance of transformers on site.

GDYZ-302W Metal Oxide Arrester (MOA) Tester
GDYZ-302W Metal Oxide Arrester Tester is is composed of a host, a detector, and an insulating rod. The host and the detector adopt wireless communication, the communication distance is 30 meters, the host can remotely open or close the clamp head of the detector to complete the test process, and the host can display the current test value and the status of the clamp head in real time. The detector uses a micro motor to drive the opening or closing of the clamp head. The clamp head is made of high-performance permalloy, which has super anti-interference ability and is hardly affected by external magnetic fields. The resolution is as high as 1uA. The detector can be connected to an insulating rod for testing of zinc oxide surge arresters on high-voltage lines. The meter can also be used as an ultra-high-precision clamp-on leakage current meter.

GDB-II Transformer Turns Ratio Tester
According to IEC and relevant national standards, the transformer ratio test is a must-do item during the production, user handover, and overhaul test of power transformers. This can effectively supervise the quality of the transformer products during delivery and use, and prevent short circuits, open circuit, wrong connection between transformer turns, and internal failure or contact failure of the regulator switch.
For this reason, the ratio tester GDB-II developed and produced by our company makes the operation easier, complete functions, stable and reliable data, and greatly improves the test speed according to the user’s on-site use requirements on the original basis. It meets the needs of various large, medium, and small oil transformer ratio tests.

GDP-713PM SF6 Gas Dew Point Tester (Chilled Mirror Method)
GDP-713PM Portable Chilled Mirror SF6 Gas Dew Point Tester is specially designed for SF6 gas micro moisture detection. The perfect combination of high-quality dew point sensor and intelligent electronic control technology makes it successfully applied to accurate measurement of dew point under various environmental conditions.
The dew point measurement is based on the principle of chilled mirror. The water vapor in the measured gas is condensed into water or frost on the mirror surface through semiconductor cold reactor cooling. When the two-phase equilibrium of water in the gas is reached, the temperature of the mirror surface is measured at this time, that is the dew point or frost point.
Compared with other forms of dew point meter, the chilled mirror dew point meter measures the dew point temperature more accurately, and at the same time has the characteristics of good measurement repeatability, stable and reliable measurement results, and easy operation.
GDP-713PM portable cooling method SF6 gas dew point meter is a standard instrument for humidity measurement in the fields of electric power, gas, meteorology, electronics, petroleum, chemical industry, measurement, etc. It is an ideal choice for establishing a humidity standard device.
