Bulk Current Monitoring Probe
MP-50
-
The Current Monitoring probes may be used whenever RF current measurements are required. Current measurements are made by placing a current carrying conductor within the “sensing” window of the probe and measuring the probe’s output voltage with an RF detector. Calibration of the probe permits the conversion of the voltages measured to current. Current measurements can be made over the frequency range shown in the transfer impedance curve furnished with each probe. There is virtually no loading of the circuit and the technique permits normal operation of the device under test during measurements. The MP-50 can be used for the procedure for clamp injection when the common- mode impedance requirements cannot be met given in chapter 7.4 of IEC/EN 61000-4-6 „Immunity to conducted disturbances, induced by radio frequency fields”. The MP-50 can also be used as current monitor for BCI testing as per ISO11452-4, RTCA/DO-160 section 20, MIL-STD-461 and various automotive standards.

-
The current injector is one of the most versatile of the injector products. Coupled with the G5100A, or other equivalent function generator, it is capable of performing small signal load steps up to 40MHz, with very fast rising and falling edges. Using the G5100A, also allows the rise and fall times to be controlled, various waveforms or even arbitrary waveforms. This can be used to simulate the effects of many different types of loads, including high speed digital circuit loading, which is often largely dynamic.

DC Bias Current Power Supply
TH1775
-
Shenzhen Chuangxin Instruments Co., Ltd.
TH1775 is a DC Bias Current Source (or DC Magnetization Current Source) used for inductance measurement of inductors and transformer windings with DC bias current. Except for constant current output, low additional error and wide frequency response range are important for bias current inductance measurement. High frequency LCR meter could be used, when the frequency response range is wide enough. MPU controlled auto current balance technology is adopted to realize AC+DC current overlap and constant current output from 0 to ±20A. Two TH1775 can be paralleled to supply a maximum current up to 40A.TH1775 permits high frequency measurement up to 1 MHz and can be directly controlled by TH2816A, TH2817A, TH2818 and TH2819. TH1773/TH1775 with its low additional error, wide frequency response range and sweep output function is widely used in DC biased inductance measurement. TH1775 also provides a perfect solution for magnetic material analysis.

Current Pulsers and Laser Diode Drivers (Pulsed Current)
-
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.

IEC Standard Burden Sets (Current)
IEC Burden Sets
-
Testing and calibrating current transformers often requires standard burdens of reliable accuracy and stability, and burdens that are immune to stray fields and harmonics. These burden sets have been carefully designed to meet these requirements. They also provide the standard burdens required for the testing of current transformers for metering service, and for the testing (within the current rating provided by the sets) of current transformers for relaying applications, all as called for by IEC (International Electrotechnical Commission) Publication 185: 1987.
