40A Current Output Power Transformer Testing Equipment With Discharge Protection

Power Transformer Single Channel DC Resistance Tester , 40A Test Current Output , Automatic Test

I. Products Description and Application 

Transformer DC resistance test is one of the most important test item in the finished product and semi-finished product factory test, installation and hand-over test in the transformer manufacturing and in the preventive test of the electric power sector it can effectively find manufacturing defects such as looseness, strand lack and broken line in the material selection, welding and connection part of the transformer coils and the hidden danger existing after running.

In order to meet the demand for quick measurement of transformer DC resistance. Our company has developed a new generation of DC resistance tester by making use of own technical advantages, . Using the brand new third-generation power supply technology, it has small volume, light weight and large output current, etc.

Model FK-40A DC resistance tester is with a new power technology, small size, light weight, large output current(max.40A). It is controlled by a single-chip, high automation with automatic discharge function and discharge instructions. It is with high precision and can achieve a rapid measurement for the transformer direct resistance.The equipment has high accuracy and easy operation, it can realize quick measurement of transformer DC resistance.

II. Features

1. The tester has large output current (maximum 40A) and high charging voltage (can output 50V).
2. It has a wide measurement range (50uΩ-4Ω), being able to measure all inductive DC resistances of transformers and instrument transformer, etc. It is specially used to measure DC resistance for above 220KV class main power transformer .
3. The equipment has the protection and alarm function against misconnection of AC380V power supply, it will reduce the damage due to misoperation.
4. It also possesses characteristics like wide applicable temperatures, high accuracy, quake proofing, anti-interference, high stability and portability. It has an audio alarm for discharge and clear discharge indications, these function also can reduce misoperation.
