K50 LIGHTNING AND CAPACITIVE CURRENT DETECTION WIDE-BAND CURRENT TRANSFORMER
INTRODUCE
The K50 wide-band current transformer is one type impulse current sensor, it utilizes the principle of magnetic induction to convert the measured current into a voltage signal proportional to the current, with high insulation between the primary and secondary sides (electrical isolation measurement of high impulse current and high-frequency pulse current). The K50 impulse current sensor has the advantages of high accuracy, wide frequency band, high sensitivity, no need for external power supply, and convenient use, making it suitable for measuring large impulse currents and wide-band transient currents. Can be applied to the measurement of lightning current, capacitor charging and discharging current, switch and harmonic current, EMI current; It can also be used for calibration of Roche coil current sensors; Due to limitations such as grounding circuit noise and high voltage isolation, it is not suitable for situations with splitters. The main performance indicators of this current sensor have been tested by authoritative departments and have reached the advanced level of similar international products.
All models are sealed and are suitable for use in high voltage insulating oil or under vacuum. They can be connected to oscilloscopes, spectrum analyzers, power analyzers, digital voltmeters, analog-to-digital convertors, and a variety of other measuring instruments.
