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.

Energy Saving Static Converter
The ENERGY SAVING static converter serves to generate a controlled squarewave single-phase alternate voltage (low frequency: 25 ÷ 125Hz) for industrial applications requiring high load power supplied by an external matching transformer. The power supply, sectioned by remote control switch and external fuses, is fed by a three-phase electric line via uncontrolled diode bridge and filtered by inductor and capacitor battery. The DC voltage thus obtained is converted into single-phase alternating voltage via “H”-shape bridge of semiconductors in order to control impressed frequency single-phase transformers.

Injection Transformer
J2101A
The injection transformer is presently the prevalent method for connecting the network analyzer to the circuit being tested, and is primarily used for control loop stability measurements. The goal of the transformer is to inject a signal into the control loop being measured, without impacting the performance of the loop. In order to accomplish this to a reasonable degree, The transformer is isolated and therefore is capable of floating on a high voltage, such as a Power Factor Corrector (PFC), which is often close to 400VDC. Measuring voltages that exceed the voltage rating of the FRA inputs require attenuation probes.
