AEMC boasts its latest digital transformer ratiometer (DTR)—the 8510—incorporates the latest technology, improving on its predecessor, the Model 8500. It offers straightforward operation, accuracy, data storage and automatic test result documentation. Features include: PT/VT from 0.8000:1 to 8000:1 and CT from 0.8000 to 1000.0 (Auto-Ranging) ratio testing; continuity test indicates open or loose (high resistance) terminal connections; DC test mode eliminates errors due to magnetic build-up; displays ratio, test current, winding polarity, and deviation from nameplate voltage or ratio; and stores up to 10,000 test results. Applications include power, potential and current transformers.
