- The TR-Mark II is the next generation of
the legendary TR-Series which has quickly become recognized as
the World's most advanced Three Phase Transformer Ratiometer.
-
- The TR-Mark II is a rugged, lightweight
instrument that automatically measures Turns Ratio, Voltage
Ratio, Excitation Current, Phase Relationship, and Phase
Displacement.
- This fully automatic instrument can perform
precision laboratory measurements as well as function extremely
well in the field for routine maintenance testing.
- A single hook-up to the transformer is all that
is needed to run a complete series of tests because all
connections of various transformer configurations are
accomplished internally.
- The Mark II system does not require any
charts or calculations for testing. The system can test more
combinations of transformer configurations than any other system
making it the most versatile and easiest to use system
available.
- The Mark II tests one of the widest
ratio ranges available (0.8....13,000) and has the highest
accuracy of any Automatic Three Phase Ratiometer (0.08%).
