The Megger TTRU3-BASIC three phase transformer turns ratiometer is a compact and efficient tool designed for testing all types of power, instrument, and distribution transformers. It uses a step-up ratio technique to simplify turns ratio testing, eliminating the need for high voltage or complex instruments. The device operates with a single 3Ø lead-set connection, offering a range of tests such as ratio, phase shift, polarity, and magnetic balance. The TTRU3-BASIC also features a 7-inch color touchscreen, intuitive user interface, and options for printing and saving test results via USB.
This device helps detect issues like loose connections, turn-to-turn shorts, broken strands, and winding deformation. With guaranteed accuracy of ±0.10% and an easy-to-use interface, it can handle testing under various conditions and provides automatic recognition of vector groups. Additionally, the TTRU3-BASIC is smaller and lighter than traditional ratiometers, making it more portable and cost-effective. It is ideal for routine maintenance, factory validation, and troubleshooting.
