With features like automatic self-calibration and compliance with EN61010-1 standards, it’s the ultimate tool for reliable transformer testing. ## Description The Megger TTR20 hand-held transformer turns ratio test meter measures the turns ratio, excitation current, and polarity of single- and three-phase power, potential, and tapped transformers. This digital meter has automatic range selection for flexibility and ease of use. The tester automatically self-calibrates prior to performing each test for increased safety and accuracy of results. The unit measures turns ratio from 0.8:1 to 10,000:1, excitation current from 0 to 100mA, and indicates normal or reversed polarity. The tester is safety rated to European Standard/International Electrotechnical Commission (IEC) EN61010-1. The TTR20 is used by electricians and electrical contractors. Specifications Power supply (6) AA batteries Turns ratio range 0.8:1 to 10,000:1 Turns ratio accuracy (0.8 to 2,000) + or – 0.1% Turns ratio accuracy (2,001 to 4,000) + or – 0.15% Turns ratio accuracy (4,001 to 10,000) + or – 0.25% Excitation current range 0 to 100mA Weight (including batteries) 1.3kg/2.8 lb. Safety standard met International Electrotechnical Commission/European Standard EN61010-1 Dimensions 240 x 115 x 50mm/9.5 x 4.5 x 1.9 inches (H x W x D)H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Electrical test meters report electrical circuit properties, such as voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, they detect electrical problems in equipment, wiring, and power supplies. A variety of probes, clamps, or leads connect the meter to a circuit or device. Single-function meters, such as battery testers and voltage testers, measure one property of a circuit; multimeters measure multiple properties. Electrical test meters display information either in analog form using a needle that moves on a calibrated scale, or in digital form using digits or a graphic representation on an LED screen. Meter choice includes the electrical properties to be measured and the anticipated range of results, and should have a rating that is higher than the maximum value of the anticipated range. An electrical test meter has multiple settings that correspond to potential ranges of values for the properties it can measure. A manual ranging meter requires the operator to flip through different settings until the correct range is reached. An autoranging meter cycles through range settings automatically until it reaches the correct range. Megger manufactures equipment for cable fault locating, protective relay testing, telecommunications and data integrity, and power quality testing under multiple brand names, among them Megger, Biddle, States, and AVO. The company, founded in 1889, is headquartered in Dover, England, and meets International Organization for Standardization (ISO) 9001:2008 standards.
