AEMC 8510 DTR Digital Transformer Ratiometer, 0.8000 to 8000:1 Ratio Range

Brand: AEMC

Features:

• Ratio testing: PT/VT from 0.8000:1 to 8000:1 and CT from 0.8000 to 1000.0 (auto-ranging)
• Tests performed by exciting the primary and reading the secondary; provides safer conditions for the operator on step-down transformers
• Continuity test indicates open or loose (high resistance) terminal connections
• DC test mode eliminates errors due to magnetic build up
• Stores up to 10 primary/secondary nameplate voltages to use in comparing test results

Details: The DTR model 8510 is a portable digital transformer ratiometer designed for on-site testing of power, potential and current transformers. When connected to a non-energized transformer, the DTR model 8510 accurately measures primary to secondary turns ratio, while simultaneously displaying polarity and excitation current. The DTR is fully automatic and uses an ANSI/IEEE compliant test method. No user calibration, range selection, hand cranking or tedious balancing is required. At each measurement, the DTR automatically self-calibrates and checks for open windings/connections/circuit breakers, short circuits (excess excitation current), incorrect test lead placement, and reverse polarity. Measurements are displayed quickly and accurately. Displays ratio, test current, winding polarity, and deviation from nameplate voltage or ratio. Stores up to 10,000 test results. DataView software included which allows configuring the instrument, downloading stored measurements and printing of test results in a report format. Display warns of incorrect lead connection, reverse polarity, open and short circuits. Applications: power transformers, potential transformers, current transformers. Ratio range (CT) 0.8000 to 1000.0 (auto-ranging). Accuracy (CT) +/- 0.5 percent. Excitation signal: VT/PT Mode: 32Vrms max; CT Mode: Auto Level 0 to 1A, 0.1 to 4.5Vrms. Excitation current display: 0 to 1000mA range; Accuracy: +/- (2 percent of Reading + 2mA). 70Hz excitation frequency. Dual line alpha-numeric LCD, 16 by 2 characters with contrast adjustment and backlight control. Day/night visible. Measurement method: In accordance with IEEE Std C57.12.90TM-2006. Power source: Two 12V, 1650mAH NiMH rechargeable battery packs. Battery life: Up to 10 hrs of continuous operation. Low battery indication. Battery charger: universal input (90 to 264Vrms input) smart recharger. Communication: USB. 2.0 compliant, optically isolated, 115.2 kb.
