Product Overview

RENT Megger TTR310E Three Phase Transformer Turns Ratio Test Set (Call for Availability)

    The Megger TTR310E three-phase transformer turns ratio test set is designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment.  Their unique testing procedures and storage capability allows an operator to set up and test difficult three-phase transformers (with multiple tap changers and bushing CTs) in a fraction of the time than it used to take with other TTRs. The TTR310E has the ability to store test results, upload results to a PC (via RS232 serial port, Ethernet or USB), and/or print them in the field via optional thermal paper printer, without the use of an external computer. 

    The most popular in the series, the Megger TTR310E features an easy-to-read, transflective color display which can be seen in bright sunlight and provides the user interface for instrument set-up and test operation. The TTR310E applies voltage to the high-voltage winding of a transformer and accurately measures the resulting voltage from the low voltage winding. In addition to turns ratio, the units measure excitation current, phase angle deviation between the high- and low-voltage windings and percent ratio error. Testing can be performed in a remote control manner with PowerDB LITE. 

Features of the Megger TTR310E Three Phase Transformer Turns Ratio Test Set Include:

• Fully automatic operation (either stand-alone or remote-control)
• Built-in RS-232 port and optional thermal spool-paper printer allows for printing of test results, while in the field, and without the use of an external computer
• Built-in capability for storing test results into internal memory in an open data format for direct input into Excel® or XML format via PowerDB LITE
