Transformer Performance Tester
6691
-
applying ±90V voltage on the winding of the transformer demagnetized and get the voltage value on the terminal and the current value in the winding to draw the hysteresis characteristic curve. This method can be used for linear quantitative analysis of residual magnetism in transformers, and fast demagnetization can be achieved by tracking hysteresis curves. The analyzer can measure magnetism residual rate before and after demagnetization.

Transformer Winding Resistance Tester
KRI 9310
-
KRI 9310 adopt Kelvin four-wire testing method, which effectively eliminates the influence of the resistance of the test line on the test results. It can be able to increases the current to 10A by which can test extremely low resistance to 0.01 Ω(such as amorphous alloy, Copper-nickel, nickel-chromium-iron, iron-chromium-aluminum etc). For the tested objects with high resistance value (CT/PT), the instrument can extend the range to 20 kΩ,so the wide resistance test range enables KRI9310 can cover 80% of the power transformer products on the market and switchgear bus-bar cable etc. The power of the tester use the built-in rechargeable lithium battery that can test hundreds of transformers by one time charging.

Transformer Degaussing Analyzer
KRI6691
-
The KRI6691 transformer degaussing analyzer injects current into the test winding by applying ±90V voltage, and collects the terminal voltage and winding current to draw the hysteresis characteristic curve. Linear quantitative analysis of transformer remanence can be performed, and rapid demagnetization can be achieved by tracking the hysteresis curve.

Extra-Ground Current Impuision Equipment
JYQ
-
Generally, the way of finding out the iron core ground false of powertransformer is always inefficient, while the method of using the traditional measure such as increase powerful current by welder when finding the false point oftransformer. The transformer needs to be mended on the spot or return to the factory if it can not melt off the point because of low voltage. It will spend high transportation fee and dealing costs, brings huge economic loss. The JYQ iron-coreimpulsionequipment is the intelligence set for exclusiveusing in solving the false of transformer. It can output high-voltage powerful current transientand melt the ground point off rapidly.
