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.
