Model
TR-Spy Mark II
Fully Automatic Three Phase Transformer
Turns-Ratio Meter |
|
|
Description |
The TR-Spy Mark II is a fully enhanced automatic
three phase turns ratiometer. The system is easy to use and
has many useful features such as the large memory base, external
control for tap changer testing, and an automatic voltage
level detection test.
- There are over 1,300 memory locations available to allow
the end-user to store over 100 complete transformer tests.
That means you can store a three phase transformer with
32 taps, all of the nameplate data, operator, location tested
etc… in one storage location. This data can be accessed
later for downloading and report generation. The system
can also deliver more current for the testing of CTs.
- The test set has 4 test voltage levels: 1, 10, 40 &
100 V and Automatic mode, which is used for most transformers
to allow maximum accuracy at an optimum output power level.
The system can be set up to test a transformer with multiple
taps with the press of one button and save the data automatically.
- The TR-Spy Mark II is a microprocessor based Single and
Three Phase Transformer Turns Ratio Test set. This system
is designed to give highly accurate readings in the field
with laboratory precision. It is the most accurate system
available.
