Product Introduction

Brief Description:

Turns Ratio & Winding Resistance Tester is focusing on two core tests: DC resistance and turns ratio group of transformer winding. It adopts high-precision signal processing technology and is equipped with a high-precision core chip. This establishes a stable and reliable measurement foundation, providing substantial assurance for the accuracy and stability of the data; Featuring the smart quick intelligent power test system (Soft No. 1010215, trademark registration number 14684781), It is mainly used in power system transformer commissioning tests, overhaul tests, and daily maintenance and inspection.

Features

• Supports one-time wiring to complete the DC resistance test and ratio test, convenient and efficient operation.

• The DC resistance test function is suitable for Yn-type, Y-type and △-type winding. Measurements can be completed through the three-phase automatic test mode, and the three-phase imbalance rate can be calculated automatically; the Max. output current is 20A, accurately meeting the testing requirements of the extremely low resistance value of the low-voltage coil of the distribution network transformer.

• The transformer ratio testing function covers three-phase, single-phase, and Z-type transformers, and is able to measure PT/CT ratio and determine polarity, and supports blind testing.

• Equipped with an embedded Linux operating system, the system boasts strong stability and high security.

• It adopts an A7+M4 dual-core architecture to efficiently process measurement data and operation commands, ensuring the real-time performance and accuracy of measurements.

• One-click result printing: Smart printing makes test result output more efficient and convenient.

• Equipped with a 7-inch large touch screen, high display, bringing a comfortable and convenient human-computer interaction experience.

• Built-in high-capacity lithium battery to meet the needs of long-term continuous testing on site.

• Equipped with a variety of wired and wireless communication interfaces, easy to expand the instrument function.•
