MEASTEK HCTL300KA High Frequency Flexible Current Probe High Voltage & Ultra High Current Measurement for EHV Power Systems
1.High-frequency detection capability: 10MHz bandwidth can detect high-frequency sinusoidal current waveforms. In the current monitoring of ultra-high voltage transmission lines, it can effectively capture high-frequency interference current signals and provide data support for ensuring the stability of power transmission.
2. Accurate measurement of tiny currents: 0.02mV/A sensitivity, 1% typical accuracy, can measure tiny current changes, suitable for monitoring weak current signals of ultra-high voltage power equipment, and timely discover potential equipment failures.
3. Ultra-high withstand voltage characteristics: 10KV insulation withstand voltage, suitable for current measurement of ultra-high voltage power systems with large current and ultra-high voltage, can work safely and reliably in ultra-high voltage environments, and ensure the safety of the measurement process.
4. Flexible installation advantages: The outer diameter of the probe ring is 8mm, soft and freely pluggable. In the distributed current monitoring scenario, it is convenient to install in ultra-high voltage poles and towers, etc., which is convenient for comprehensive current monitoring of ultra-high voltage lines.
5. Convenient connection and power supply: USB power supply, easy to use, standard BNC output interface is convenient for connecting professional measurement equipment, realizing ultra-high voltage power system current data collection and analysis, and providing strong support for power operation and maintenance.
