Device Current Waveform Analyzers
The dedicated Current Sensors measure from 100 pA level dynamic current up to 10 A with a maximum of 200 MHz bandwidth. The mainframe acquires the signal from the sensors by a maximum of 1 GSa/s sampling speed and 14-bit and 16-bit wide dynamic range. This combination allows you to measure quite wide range of dynamic current, for example, from standby/sleep state to active state, at a single measurement. In addition, the wide bandwidth and the high speed acquisition enable you to measure high speed pulse response even less than 100 ns previously very difficult with existing instruments.

High Frequency Current Transformers
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.

Lightning Current Generator
Shanghai Guantu Technology Co., Ltd.
The lightning wave impulse current generator is an impulse current generator that generates a simulated lightning current waveform . Its working process is as follows: first, the transformer charges the capacitor bank through the silicon pile, when the charging voltage reaches a predetermined value, the spark gap is triggered, and the capacitor is discharged through the total inductance and total resistance of the circuit. When the resistance is greater than or equal to the critical damping value, a unidirectional impulse current wave is generated in the circuit. When the resistance is less than the critical damping value, an oscillating impulse current wave is generated. The magnitude of the impact current amplitude is related to the circuit parameters. When the capacitance value and charging voltage are the same, the smaller the inductance value, the greater the current amplitude. In order to obtain as much current as possible, a pulse capacitor with a small inductance value is usually selected, and the total length of the connecting line should be as short as possible when arranging the main capacitor, so that the total loop inductance value can be reduced as much as possible.

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.
