Transformer Test Equipment

The RDKC-2000 transformer on-load tap-changer is the only moving part connected to the transformer circuit. Therefore, the detection of the on-load tap-changer is becoming more and more important. In the "power equipment transfer and preventive test procedures", asked to check the on-load tap-changer action sequence, measurement switching time. The instrument is mainly used to measure the transformer on-load tap-changer transition waveform, transition time, the instantaneous transition resistance, three-phase synchronization and so on.
The instrument is highly intelligent, menu prompts, simple operation. Instrument small size, light weight, anti-interference ability, greatly reducing the labor intensity of the site staff, is the power supply units, transformer manufacturing industry to ensure safe production, improve product quality ideal instrument.

The anti-interference pilot frequency dielectric loss tester is a high-precision instrument for testing the dielectric loss tangent and capacitance of various high-voltage power equipment in power plant, substation and other field or laboratory.
The Capacitance Dielectric Loss & Dissipation Factor Tester is an integrated structure with built-in dielectric loss test bridge, variable frequency voltage regulating power supply, step-up transformer and SF6 high stability standard capacitor. The test high-voltage source is generated by the inverter inside the instrument, which is used to test the tested object after boosting by the transformer. The frequency can be 45Hz or 55Hz, 55Hz or 65Hz, 47.5 or 52.5Hz. The digital notch technology avoids the interference of power frequency electric field on the test, and fundamentally solves the problem of accurate measurement under the interference of strong electric field. At the same time, it is suitable for the situation of power supply detection by generator after all power failure.

In the production process of semi-finished and finished power transformers, before the newly installed transformers are put into operation and according to the preventive test regulations, it is required to test the turn ratio or voltage ratio of the running transformers, so as to check the correctness of the turn ratio of transformers, the condition of tap changer, whether the transformers are short circuited between turns, and whether the transformers can operate in parallel.
The traditional bridge reading is not intuitive, so the conversion can only be carried out phase by phase. RDB-Ⅲ transformer ratio tester overcomes the shortcomings of traditional ratio bridge test, which is easy to operate and intuitive. TTR tester adopts three-phase precision inverter power supply, and has fast test and high accuracy.

Transformer Demagnetization Tester is a special equipment to eliminate the remanence after the DC resistance test of a large power. It is very important to protect the transformer from the impact of the inrush, the safe operation and the prolongation of the life of the transformer.
Our Transformer Degaussing Test Kit，Adopt advanced and reasonable compound current method technology，demagnetize power transformer，the demagnetization detection is also quantified
