Page 57: Application Notes
A. Application Notes A.A Real Three Phase Voltage Option T-Rex The Raytech Real Three Phase Voltage Option T-Rex is an optional system accessory for 3- Phase transformer ratio meter test sets designed by Raytech (i.e. TR-MARK III). T-Rex was designed to allow Engineers and Test Technicians the ability to test the phase relationships and actual voltage ratios of transformer windings while applying three phase voltage. -
Page 58: Current Transformer Testing
A.B Current Transformer Testing A.B.A Introduction Current transformers are, in effect, opposite wound voltage transformers. This basically means that the largest number of windings are on the “X” (low current) side of the current transformer. The TR-MARK III applies a voltage (from 1 to 100 VAC) from the “H” leads and measures back through the “X”... -
Page 59: Low Impedance
2: Select CT Testing, use 10 (normal), 3: Touch Go A 40V (high ratio) or 1V (low impedance) A.B.C Low Impedance In certain cases, where the impedance (inductance) of the CT is so low that TR-MARK III gets to its power limits, an “Overcurrent” Message will be displayed on the screen. It is then recommended to run the test with a lower test voltage. -
Page 60: Test Reports
B. Test Reports Test Reports are printed results of TR-MARK III. The following two chapters show test reports. Please see chapter ‘8.1.2.3 Print and Save, Turns Ratio or Voltage Ratio’ about how to print. To use the external instead of the internal printer, just connect a printer to USB port of TR-MARK III. -

A device with this option can be recognized by having a 6 pin Lemo ‘Extern’... -
Page 63: A Look Under The Hood
C.A A Look under the Hood The Extended Safety Interlock is nothing else, than the access to the internal safety interlock of TR-MARK III. An open external interlock line will have the same effect to the device as a pressed emergency switch. Please see the following schematic as an additional explanation: Of course, when using an 70049-A device that is not connected to en external interlock line, the use of a dummy plug is necessary. -

Is the Emergency stop switch pushed in? Turn to release it. Measurement Accuracy sometimes is not good: The Raytech TR-MARK III 250V has been designed and tested to be immune against electromagnetic disturbances. However in rare cases, in presence of strong radio frequency electromagnetic field, turn ratio measuring accuracy may be degraded depending on field amplitude and frequency band. -
