Product Overview
The XZH TEST XHZ1010S is a professional-grade Transformer DC Resistance Tester engineered for precision winding resistance measurement in manufacturing QA, field commissioning, and routine maintenance environments. With a robust 10A test current output, 0.2% accuracy, and 0.1μΩ resolution, this instrument delivers the reliability and repeatability required for critical power transformer diagnostics.
Transformer DC resistance testing is an essential procedure throughout the equipment lifecycle — from semi-finished and finished product quality control, factory acceptance testing, and on-site installation verification, to post-overhaul inspection and tap changer modification validation in power systems.

Key Features
Advanced Power Supply Technology — Compact, lightweight design without compromising output power, ideal for both lab bench and field deployment.
High Output Current with Excellent Repeatability — 10A maximum test current ensures stable, reproducible measurements even on large transformer windings with high inductance.
Strong Anti-Interference Capability — Comprehensive protection circuits guard against overvoltage, overcurrent, and misconnection, ensuring safe operation in high-EMI substation environments.
Automated Microcontroller Operation — One-touch auto-ranging with 7 current levels (AUTO, <20mA, 40mA, 200mA, 1A, 5A, 10A) intelligently selects the optimal range for each measurement.
Built-in Automatic Discharge & Alarm — Safely dissipates residual winding energy after each test, with audible and visual alerts upon completion.
High-Resolution 320×240 65K Color LCD Display — Crisp 4-digit resistance readout with backlight ensures clear visibility in both bright outdoor and dim indoor conditions.
Onboard Data Storage for 1000 Test Records — Eliminates manual logging; review and export historical data for trend analysis and compliance reporting.

Frequently Asked Questions
Q1: What types of transformers can the XHZ1010S test?
The XHZ1010S is suitable for all types of power and distribution transformers, including oil-immersed, dry-type, and cast-resin transformers. It handles both delta and wye winding configurations across a wide resistance range from 0.5 mΩ to 20 kΩ.
Q2: How long does a typical winding resistance test take?
Test duration depends on winding inductance. For small distribution transformers, measurements stabilize within 5–15 seconds. For large power transformers with high inductance windings, the auto-ranging algorithm typically completes within 30–90 seconds per phase.
Q3: Is the XHZ1010S suitable for field use in substations?
Yes. The XHZ1010S is specifically designed for field deployment. It features a built-in rechargeable lithium battery for full-day operation, a rugged enclosure rated for 0°C–40°C environments, strong EMI immunity for high-voltage substation conditions, and automatic discharge circuitry for operator safety.
Q4: What after-sales support and warranty do you provide?
XZH TEST provides a 12-month standard warranty on the XHZ1010S covering manufacturing defects. We offer lifetime technical support via email and phone, calibration services, and optional extended warranty plans. OEM/ODM customization is available for volume orders — contact our sales team for details.
Q5: What is the minimum order quantity and typical lead time?
The minimum order quantity is 1 unit — we support both sample evaluation and bulk procurement. Standard lead time is 5–8 working days after order confirmation. Larger quantities may qualify for volume discounts; please request a quotation for your specific requirements.
