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.

Winding Resistance Tester
JYR20S/10S
DC winding resistance testing is regarded as another essential routine screening tool. It indicates problems such as loose, defective or incorrect connections, which cause enough transformer failures each year to be regarded as a failure category of its own.

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.

Earthing Resistance Tester
JYD-10A
transformer neutral grounding resistor is the vital need in medium voltage AC distribution network that are also called by different names like Neutral Earthling Resistors. They are taken into use to limit the current that would flow through the neutral point of a transformer or generator in the event of an earth fault. They are also used for resistance grounding of connected generators and transformers.

Contact Resistance Tester
JYL
As a high current passes through a pair of mechanically independent metallic contacts, the contact resistance must be as low as possible. Increasing the contact resistance of the contact often causes a large voltage drop on the contact, which reduces the input power of the load equipment. If the contact resistance of one or two contacts becomes large, the three-phase voltage of the load equipment will be unbalanced, causing phase loss operation.

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.
