TR-MARK III R 250V
Turns Ratio Meter 3 Phase Rack
Description
The Raytech TR-MARK III R 250V is the rack-mounted version of TR-MARK III 250V which is designed more for laboratory or test van systems as a part of the Raytech ATOS system. It is a 3-phase power transformer test instrument specially designed for professional turns ratio measurement. The professional turns ratio measurement is not just a typical pass/fail test to check that the deviation error is less than the limit values! For precise diagnosing and preventive maintenance, high precise measurement is required. In addition to precision, the TR-MARK III R 250V provides useful tools such as a plotting tool on the colour touch display, or a fully remote software control for this aim.
The TR-MARK III R 250V can perform the full turns ratio measurement in the least possible time and in a fully automatic easiest way. For a three-phase two-winding power transformer, only one time hook up of the test clamps is required. Additionally, by using the Raytech MUX-R in ATOS, the same cables for winding resistance and turns ratio measurement can be used even for transformers with tertiary windings.
The on-load tap changer or motorized de-energized tap changer can be controlled automatically by the instrument. Even the actual tap position can be identified automatically, thanks to the smart features of the TR-MARK III R 250V. The full three-phase measurement of the turns ratio, excitation current, phase displacement and calculated deviation error for all taps can be performed fully automatic without the interaction of the user during the measurement.
