Transformer Turns Ratio Tester(Handheld)
Uses
The Transformer Turn Ratio Tester is a handheld, tool-style device powered by a built-in rechargeable lithium-ion battery. It is suitable for measuring the turn ratios of everything from distribution transformers to 1000 kV transformers, current transformers (CT), voltage transformers (PT), and Z-connected transformers, and can perform tests on hundreds of transformers on a single charge. It is the ideal transformer turns ratio tester for power systems, transformer manufacturers, and the railway system.
Function
1.Suitable for measuring the turns ratios of transformers ranging from distribution transformers to 1000 kV transformers, current transformers (CT), voltage transformers (PT), and Z-connected transformers
2.The interface features an intelligent touchscreen design, making it simple and convenient to use.
3.The circuitry employs a new-generation, fully digital design to ensure the instrument’s long-term stability.
4.The instrument is powered by a built-in lithium battery and can perform tests without an external AC power source.
5.Fast testing: A single connection is all it takes to complete a three-phase turns ratio test in just 10 seconds.
6.It features multiple built-in short-circuit measurement modes, making it easier to diagnose faults.
7.Features a blind test function that allows for transformation ratio and connection group testing without entering any parameters
8.Powered by a lithium battery, with automatic output voltage regulation and soft-start and soft-stop functions
9.Non-volatile clock and date display; the device can store up to 100 sets of data, which are retained even during a power outage.
10.Large-screen color LCD display with clear, easy-to-read data
11.Equipped with an RS-485 communication interface and a USB flash drive storage interface
12.The instrument features high- and low-voltage reverse connection protection, as well as protection against transformer short circuits and inter-turn short circuits.
13.Smart charging management, remaining battery level display, low battery alert, and power-saving features
14.The Bluetooth communication module enables data exchange with host computers such as PCs or connects to a micro Bluetooth printer to print data reports (optional)
