Lithium Battery Powered Handheld Transformer DC Resistance Tester Touchscreen| XHZ1010SC

The XHZ1010SC Handheld DC Resistance Tester is an essential tool for transformer testing scenarios, including factory tests for semi-finished and finished products, installation, maintenance, tap changer changes, commissioning, and preventive checks by power sectors. It validates winding joint welds, detects inter-turn short circuits, ensures proper contact of voltage tap changers, checks for broken lead wires, and identifies strand damage in multi-strand windings. Powered by state-of-the-art power supply technology, it boasts a compact, lightweight design, high output current, consistent performance, robust anti-interference, and full protection features. Driven by a high-speed MCU, it offers full automation with automatic discharge and alarm functions, combining precise testing with user-friendly touchscreen operation for quick and reliable transformer DC resistance measurement.

• Two selectable power supply modes solve the problem of on-site testing being impossible due to lack of mains power
• Automatically completes self-calibration, current stabilization judgment, data processing, and resistance display
• Longitudinal testing of DC resistance of on-load tap-changing transformers can be completed with a single power supply
• Comprehensive back EMF protection with fast measurement speed and accurate, stable data
• High-speed MCU control with full automation, automatic discharge, and alarm functions
• Simple operation, high precision, anti-interference, shock resistance, and portability

• Power systems: power generation, transmission, transformation, and distribution
• Factories and mines: large-scale manufacturing plants and various mining companies
• Metallurgy and petrochemicals: smelting, chemical processing, water treatment
• Transportation: ports, railways, highways, airports, and municipal streetlights
• Enterprises and institutions: logistics departments of large enterprises
• Construction industry: large construction and property management companies
• Power installation and testing: power installation and commissioning companies of all levels

Designed for on-site commissioning engineers, power installation and commissioning companies, and field service technicians who need an ultra-portable, battery-powered DC resistance tester for transformer testing where mains power is unavailable. With lithium battery operation, a handheld form factor, and longitudinal testing of on-load tap-changing transformers in a single pass, it is tailored for rapid field measurement of transformers and tap changers during installation, commissioning, and emergency maintenance. Unlike benchtop touch-screen models for laboratories or magnetization models for large transformer rapid testing, this model emphasizes battery mobility, one-pass on-load tap changer testing, and rugged shock resistance for demanding field environments.

• Wait until the discharge is complete and the warning sound stops before disconnecting the wires, otherwise it may be dangerous.
• When measuring a no-load tap-changing transformer, always reset and discharge before switching taps; switch taps only after the warning sound stops.
