Description

Enhance your substation diagnostics and preventative maintenance protocols with the Megger TTR 550503, a fully automatic, three-phase transformer turns ratio test set engineered for precision in demanding industrial environments. Designed for fast, accurate field testing, this rugged instrument provides highly reliable measurements for power, voltage, and current transformers.

When conducting routine maintenance or urgent overhauls on high-capacity equipment—from standard 630 KVA distribution units to larger 3500KVA power transformers—the Megger TTR 550503 delivers unparalleled diagnostic confidence. It seamlessly measures turns ratio with an exceptional accuracy of 0.1%, along with phase angle deviation and excitation current. This makes it an indispensable tool for identifying underlying internal issues like shorted turns, core faults, or defective tap changers. The system automatically calculates and displays the percentage error against the transformer’s nameplate, significantly reducing the margin for human error during complex on-site testing.

Built for workflow efficiency, this portable tester features onboard storage for up to 200 three-phase test results, allowing engineers to easily download data to a PC for comprehensive reporting. Optimize your electrical testing capabilities, ensure the stability of your power network, and safeguard critical infrastructure with this advanced diagnostic solution.
