Transformer Test Equipment

The DC resistance test of transformers is a must-test item for semi-finished products, finished products factory test, installation, handover test and preventive test of power department in transformer manufacturing. Dual-channel DC Resistance Tester can effectively discover whether there are manufacturing defects such as looseness, missing stocks, wire breakage, etc. in the selection, welding, and connection of the transformer coil and hidden dangers after operation.

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 RDZR-10A transformer DC resistance tester is a necessary test item for semi-finished product, finished product factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department in transformer manufacturing.
Our Transformer dc resistance test instrument can check the welding quality of the winding joint and whether there is inter turn short circuit in the winding, whether the contact of each position of the voltage tap changer is good.

The RD8100B transformer core grounding current tester can measure the transformer core grounding current and leakage current online (range: 0.00mA~100A).The current clamp is made of magnetic shielding material with strong anti-interference ability. The inner diameter of the clamp is 80mm×80mm. It can clamp cables or ground wires below Φ80mm or 96mm×4mm Flat steel ground wires.

In the production process of semi-finished and finished power transformers, before the newly installed transformers are put into operation, 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.

The RDZR-10A transformer DC resistance tester is a necessary test item for semi-finished product, finished product factory test, installation, overhaul, change of tap changer, handover test and preventive test of power department in transformer manufacturing.
RDZR-10A Dc resistance tachometer can check the welding quality of the winding joint and whether there is inter turn short circuit in the winding, whether the contact of each position of the voltage tap changer is good, whether the actual position of the tap changer is consistent with the indicated position, whether the outgoing line is broken, and whether there is broken strand in the parallel winding of multiple wires.
In order to meet the needs of fast measurement of transformer DC resistance, our company developed RDZR-10A DC resistance tester. The DC resistance test instrument adopts new power supply technology, which has the characteristics of small volume, light weight, large output current, good repeatability, strong anti-interference ability, perfect protection function and so on. The whole machine is controlled by high-speed single-chip microcomputer, with high degree of automation, automatic discharge and discharge alarm function. The DC resistance tester of transformer has the advantages of high precision and easy operation, and can realize the fast measurement of transformer direct resistance.

RDB-IIH portable transformer turn ratio tester overcomes the shortcomings of traditional ratio bridge test, which is easy to operate and intuitive. It adopts three-phase precision inverter power supply, and has fast test and high accuracy.

In the production process of semi-finished and finished power transformers, before the newly installed transformers are put into operation, 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.
