MS0110 Power Transformer Parameter Tester (DC Resistance + Turns Ratio + Energy Efficiency Class)

Currently, during the scheduled maintenance of transformers, the assessment of energy efficiency ratings, DC resistance testing, turns ratio and vector group testing, and insulation resistance testing are all mandatory inspection items. To perform these various tests and operations, it is typically necessary to separately deploy a dedicated energy efficiency tester, a DC resistance tester, and a turns ratio and vector group tester. This implies that for every maintenance cycle, personnel must transport three distinct instruments. Since these three devices function as independent units—each equipped with its own dedicated test leads—the actual testing process necessitates a sequential, step-by-step approach involving frequent reconfiguration of wiring connections. Consequently, this results in a significant waste of manpower, material resources, and working hours.

To address this challenge, a comprehensive testing system for distribution transformers has been developed that integrates three core functions—"DC Resistance + Turns Ratio/Vector Group + Energy Efficiency Rating"—into a single unit, powered by a high-capacity lithium battery. With just this single device, all three distinct testing tasks can be completed in a single operation, thereby completely eliminating the cumbersome procedures of repeatedly dismantling and reconnecting test leads.

1. A single wiring setup is sufficient to complete DC resistance testing, turns ratio testing, and intelligent testing functions.

2. DC Resistance Testing Function: Supports an automatic three-phase testing mode for Yn, Y, and △-type windings, and automatically calculates the three-phase unbalance rate. With a maximum output current of 20A, it is fully capable of meeting the testing requirements for the extremely low resistance values found in the low-voltage windings of distribution transformers.

3. Turns Ratio Testing Function: Features testing capabilities for three-phase, single-phase, and Z-type transformers; supports turns ratio and polarity testing for PTs/CTs; and includes a "blind testing" function.

4. Energy Efficiency Class Testing Function: Integrates capacity, load, no-load, and zero-sequence impedance testing functions into a single unit, enabling precise measurement and determination of a distribution transformer's energy efficiency class.

5. Equipped with a variety of wired and wireless communication interfaces to facilitate future functional expansion of the instrument.

6. Runs on an embedded Linux operating system, characterized by high security, smooth performance, and ease of operation.

7. The instrument utilizes an A7 + M4 dual-core architecture, ensuring both real-time measurement capabilities and the smooth, efficient operation of the system.

8. Features a large, industrial-grade 7-inch display screen with a clean and minimalist interface design; combining full touch-screen control with a "one-touch shuttle" rotary knob, it delivers a comfortable and convenient human-machine interaction experience.

9. The instrument is powered by a high-capacity lithium battery and features a built-in charging module.
