High Voltage Cable Dielectric Loss Tester
Product Introduction
High-Voltage Cable Dielectric Loss Tester, primarily designed for factory testing of high-capacity and high-voltage capacitive equipment such as high-voltage motors, high-voltage bushings, and high-voltage cables. It performs dielectric loss testing under external high-voltage application environments utilizing external high-power test transformers or series resonance devices. The instrument consists of a handheld terminal and a test host. Communication between the handheld terminal and test host utilizes 2.4 GHz wireless technology. It supports both forward and reverse connection testing methods, with current measurement ranges for both methods spanning an exceptionally wide range of 2 μA to 15 A. The device automatically adapts to measure externally applied high voltages at different frequencies, covering a range from 30 Hz to 300 Hz.

Product feature and application
• 7-inch Color LCD Industrial-Grade Capacitive Touchscreen
The instrument features a high-end capacitive touch 7-inch color LCD display. The oversized interface presents all operation steps via English menus, ensuring each step is clear and straightforward.
• Ultra-Wide Current Range
Both direct and reverse connection current measurement ranges cover an ultra-wide span of 20μA to 15A. Higher current ranges are available upon request.
• Ultra-wide frequency range
External high-voltage frequency spans an ultra-wide range of 30Hz-300Hz with adaptive measurement.
• Customizable high-voltage options
External high-voltage output accommodates diverse high-voltage environments and can be customized per user requirements.
• Fiber-Optic High-Voltage Communication
Industrial-grade fiber-optic communication modules connect high-voltage and low-voltage sampling between the test host, ensuring insulation between voltages while maximizing measurement accuracy.
• Independent Handheld Operation Terminal
The handheld terminal communicates with the test host via fully isolated 2.4GHz wireless. Users operate entirely through the handheld terminal during testing, maximizing operator safety.
• Lithium-Ion Battery Power
The handheld terminal, low-voltage end of the test host, and high-voltage end of the test host are all powered by lithium-ion batteries. A full charge enables continuous operation for over 8 hours.
• USB Flash Drive Storage
Data stored locally can be saved to a USB flash drive via the USB interface.
Prodection details
Suitable for factory testing of high-voltage capacitive equipment such as high-voltage motors, high-voltage bushings, and high-voltage cables, requiring external voltage-application equipment (e.g., high-power test transformers, series resonant devices) to conduct dielectric loss testing.
Company Qualifications
1)What are the two components of the MOEORW-W901 High-Voltage Cable Dielectric Loss Tester, and how do they communicate?
Answer: This instrument consists of a handheld terminal and a test host. Both utilize 2.4G wireless communication, enabling remote operation to ensure operator safety.
2)What is the power supply method for the MOEORW-W901 High-Voltage Cable Dielectric Loss Tester? How long can it operate continuously after a full charge?
Answer: The handheld terminal, low-voltage end, and high-voltage end of the test host are all powered by lithium batteries. After a full charge, it can operate continuously for over 8 hours, meeting the needs of extended testing.
3)When using the MOEORW-W901 High-Voltage Cable Dielectric Loss Tester, what are the possible causes of the "Host Abnormal" prompt?
Answer: The core cause of this prompt is abnormal wireless communication between the handheld terminal and the test host. Specific possibilities include: 1.
