The DTR

Model 8500 from AEMC

Instruments is a portable digital trans-

former ratiometer designed for on-site

testing of power, potential and current

transformers. When connected to a

non-energized transformer, the DTR

Model 8500 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.

The DTR

Model 8500 is designed

with operator safety in mind. Tests

are performed at low voltage and,

unlike other ratiometers, step-down

excitation is employed. This method,

in conjunction with an integral H/X

reverse protection circuit, guards

against the generation of hazardous

test voltages normally associated

with transformer ratio measurement

instruments.

A large, dual line alpha-numeric LCD

display with adjustable contrast and

backlight guarantees day/night read-

ability. Power is supplied by integral

NiCD battery (included) or by AC line.

Batteries are charged automatically

during AC operation.

Both rugged and reliable, the DTR

Model 8500 is built into an attractive,

sealed structural polypropylene case

designed to withstand the rigors of

utility and industrial field use.

Constructed using only the highest

quality electrical and mechanical

components, the DTR

Model 8500

sets the standard in advanced design,

engineering and workmanship, and it

will provide the user with years of

accurate and reliable measurements.
