Features and Advantages
1.Wireless Transmission for Safe Long-Distance Testing
The primary high-voltage current clamp adopts wireless transmission with a distance up to 100 meters, avoiding close contact with high voltage and greatly improving operation safety.
2.Strong High-Voltage Insulation, Wide Application
Equipped with an insulation rod that withstands voltage up to 110kV, suitable for testing insulated wires below 60kV and bare wires below 35kV, ideal for substations, power plants, industrial and mining enterprises.
3.High Precision & Strong Anti-Interference
The clamp is made of high-performance permalloy with magnetic shielding technology, resisting external magnetic field interference. The accuracy of primary/secondary current measurement reaches ±0.5%FS, ensuring stable and reliable readings.
4.Multi-Function Integration, All-In-One Device
Simultaneously measures high/low voltage current, transformation ratio, phase, polarity and error, also functions as a high-low voltage clamp meter and high-altitude current tester.
Convenient Operation, Time-Saving & Efficient
5.Unique automatic plug-in structure for the high-voltage clamp enables quick clamping/retracting with the insulation rod; fully automatic range shifting without manual adjustment.
6.Large Data Storage, Easy Management
The host can store up to 3000 groups of data with power-off protection. Supports data hold, view, delete and upload to a computer via USB.
7.Clear Display, User-Friendly
128×64 dot matrix LCD with backlight ensures clear readings in bright or dark environments; intuitively displays current, ratio, phase, error and other parameters.
8.Smart Power-Saving, Long Battery Life
Auto power-off after 15 minutes of inactivity; low battery voltage reminder; easy battery replacement with anti-leakage design for long-term storage.
9.Durable Structure, Easy Maintenance
The insulation rod is moisture-proof, high-temperature resistant, impact-resistant and bending-resistant; the clamp head is easy to clean and maintain.
10.Comprehensive Safety Design
Multiple safety warnings and strict operation specifications to prevent over-voltage and over-current testing, ensuring operator and equipment safety.
