Page 3: Introduction
TRT3x Introduction 1 Introduction The purpose of this Manual is to provide helpful instructions on how to use TRT3x instrument safely, properly and efficiently. The following instructions will help the user avoid unsafe situations, reduce maintenance costs and will ensure the reliability and durability of TRT3x instrument. TRT3x must be used in accordance with all existing safety requirements and regulations based on national/local standards for accident prevention and environmental protection. -

DV Power will also void the warranty. • If TRT3x seems to be malfunctioning, please contact the DV Power Support Team (refer to the “Manufacturer Contact Information” section) after previously checking the “Error Messages” section. • Prior to connecting TRT3x, ensure that a transformer (object) to be tested is completely de-energized and isolated from both the line and the load. -
Page 5: Power Supply
TRT3x Introduction • Never exchange connections to the HV and LV sides of the transformer. The “H” connections must always be connected to the High Voltage side of the transformer. The “X” connections must always be connected to the Low Voltage side of the transformer. Interchanging any or all of the connections may result in damage to the transformer or TRT3x and is a significant safety hazard to personnel. - Page 6 TRT3x Introduction If the test object is a three-phase transformer or a three-phase autotransformer, TRT3x can apply either three single-phase test voltages in turns or a true three-phase test voltage to the transformer primary windings. Three induced voltages at the transformer’s secondary side are measured. Please note any use of TRT3x other than the ones described in this Manual are considered improper and will void the device warranty.

- Page 12 TRT3x Getting Started When generating a true three-phase test voltage, TRT3x generates a true three-phase excitation test voltage to three transformer primary windings. The induced three-phase voltages across the unloaded transformer windings are measured and the transformer turns ratio is calculated. Test voltages of 1 V, 8 V, and 10 V are recommended for current transformers (CT) testing.
