Description
Digital Transformer Turns Ratiometer Model 8511
- Precision, Accuracy, and Confidence in Every Test
- The DTR® 8511 is the next-generation digital transformer ratiometer, engineered to make transformer testing faster, safer, and more reliable than ever
- Building on the proven performance of the DTR® 8510, this enhanced model introduces modern upgrades for the field—combining rugged portability with advanced measurement technology
- Designed for Field Technicians
- No hand cranking. No calibration. No wasted time
- The DTR® 8511 was built for fast, accurate, and hassle-free testing of transformers (power, VT/PTs, and CTs)
- With its brighter display, ergonomic design, and built-in safety checks, you’ll have confidence in every result
- Why Choose the DTR® 8511?
- Wide Ratio Range - Accurately measure transformer ratios up to 8000:1 for VT/PTs and 1000:1 for CTs
- High Precision - Advanced low-voltage step-down technology ensures repeatable, reliable results
- Automatic Testing - Fully automatic cycles check for lead reversal and open circuits—no manual balancing required
- Built-In Continuity & Deviation Checks - Instantly compare measured values to stored nameplate data for clear pass/fail results
- Rugged & Field-Ready - Lightweight IP53-rated design with a bright backlit display and oversized test button for easy use—even with gloves
- Flexible Power Options - Operates on rechargeable NiMH batteries, USB-C, or 12 Vdc supply
- Large Storage Capacity - Save up to 9,801 test results for recall and reporting
- Seamless Data Management & Connectivity - Connect directly to your PC via the isolated USB interface to manage results, configure nameplate values, and generate professional reports with the included DataView® software and DTR® Control Panel
- A typical application of the DTR 8511 is checking transformer ratio winding values prior to installation by comparing nameplate values to actual values for ratio accuracy reasons
- FEATURES
- Advanced Low-Voltage Step-Down Measurement – Applies test current to the primary side windings, enhancing operator safety and enabling testing across a wider range of transformer types and sizes
- Automatic Test Cycles – Quickly checks for lead reversal and open circuits with no manual balancing required
- Built-in Continuity Testing – Detects open transformer windings quickly
- Deviation Calculations – Compare measured values to stored nameplate data for instant pass/fail results
- Large Storage Capacity – Save up to 9801 test results for easy recall and reporting
- PC Connectivity – Transfer data, set nameplate values and control the instrument remotely with included DataView® software
- Rugged and Portable – Lightweight, field-ready design with an IP53-rated protective case (with lid closed)
- Flexible Power Options – Operates on NiMH batteries or 12 Vdc external supply. Batteries can be recharged through USB-C connector or 12 Vdc external supply
- User-Friendly Interface – Bright backlit 4-line display, intuitive navigation keys, and audible test alerts
- Catalog Number 2136.55
