Description

The AEMC DTR 8511 (2136.55) is a portable, handheld digital transformer ratiometer engineered for on-site testing of power transformers, potential transformers (PT/VT), and current transformers (CT). Designed to eliminate the labor-intensive balancing and manual calculations associated with legacy bridge instruments, the DTR 8511 automates turns ratio, excitation current, and winding polarity measurements in a single test cycle. Its low-voltage step-down test technique prioritizes operator safety by exciting the primary winding at safe potential levels, making it an indispensable diagnostic tool for utility substations, industrial plants, and transformer manufacturing facilities. Built with robust pre-test diagnostics, the instrument automatically checks for open circuits, short circuits, high winding resistance, and reversed polarity before applying full test signals, shielding both the unit and the transformer under test from accidental damage. Technicians can pre-program up to ten standard nameplate ratios alongside a user-defined setting directly into the unit, enabling real-time error percentage calculations against manufacturer specifications. With an auto-ranging ratio measurement span up to 8000:1 and conformance to IEEE Std C57.12.90™ testing standards, it provides high-precision data essential for detecting early winding deformation, tap-changer misalignments, and core issues. Housed in a rugged, impact-resistant field case rated for tough operating environments, the DTR 8511 combines field durability with modern data management capabilities. The integrated internal memory stores up to 9,801 complete measurement records, categorized across multiple user-defined objects for clean audit trails. Powered by an internal rechargeable NiMH battery pack or universal 110V/220V line power via USB-C, the ratiometer pairs seamlessly with AEMC’s DataView® software suite to generate comprehensive, professional compliance reports, test logs, and historical trend analyses with minimal setup time.
