Page 3: Introduction
1.1.2 Terms of Use • The TRT30C shall be used only if it is in good technical condition. Its use shall be in accordance with local safety and industrial regulations. Adequate precautions must be taken to avoid any risks related to high voltages associated with this equipment and nearby objects. -
Page 4: Orderly Practices And Procedures
Hazardous voltages exist on the terminals of the TRT30C when the “Red” LED is lit. Never assume that the connections are safe even if this LED is off. Switch off and unplug the TRT30C before touching the connections, particularly if a fault is suspected. -

(e.g., L1-L2; A-B). However, the voltage must not exceed 264 V AC. Please refer to the section “Technical Data”. • The TRT30C should be positioned in such a way that it is possible to safely disconnect it from the power supply at any moment. WARNING / AVERTISSEMENT This is a class A product. - Page 6 Three induced voltages at the transformer’s secondary side are measured. Please note that any uses of the TRT30C other than the ones described in this Manual are considered improper and will void the device warranty.

Connect the TRT30C to the mains power supply with a power cord. Power switch – Double pole switch • I In this position, the TRT30C is connected to the mains power supply. • 0 In this position, the TRT30C is separated from the mains power supply. - Page 8 The TRT30C is equipped with an USB serial interface to connect to an external computer if required. Flash Drive The TRT30C is equipped with a USB flash drive connector to save the test results to the flash drive for additional analysis if desired. 7. TC Control TC Connector Output for the remote control of the transformer tap changer.

Page 9: Getting Started
• The transformer is completely de-energized. • The TRT30C itself should be properly grounded. To do this, the grounding screw on the top of the TRT30C should be connected to PE using the provided grounding cable. Note: Always connect measuring cables to the TRT30C first and then to the test object terminals. -

ENTER 1. If the vector group is selected, the TRT30C will perform both the true three-phase test by applying true three-phase test voltage and the phase by phase test by applying single phase test voltages to all phases in turn. - Page 11 Low Voltage Tap Changer position If the name plate voltages are not entered, the TRT30C will perform the test and display the results, but it will not calculate or display the turns ratio deviation. After the name plate voltages and tap changer position(s) are entered, press to confirm selection.
- Page 12 50 Hz or 60 Hz. The frequency of the output voltage is the same as the frequency of the power supply of the TRT30C. In case the TRT30C is connected to a DC power supply, the user has to choose the frequency of the output voltage to be either 50 Hz or 60 Hz.
