NRRL-C Transformer No-load & Loaded Tester (also known as transformer Loss tester), it is dedicated to measure no-load loss, short-circuit loss, zero sequence impedance, short-circuit impedance of the transformer. No-load loss and short circuit loss is an important project of generator, motor and transformer test. According to GB1094.5-85 and IEC14/268CD, the variation of short-circuit impedance is the only criterion for judging the deformation of transformer winding.
Overview
Functions and features
● The instrument can test no-load current no-load loss impedance voltage and short-circuit loss of various types of transformers.● Wide range of voltage circuit: the maximum measuring voltage is 750V without switching gears to ensure accuracy and will not damage the instrument due to choose wrong voltage level.
● Large screen high brightness of LCD display full English menu and operation tips to achieve a friendly man-machine dialogue easy to operate.
● Users can print out the test data in real time.
● Adopting digital synchronous sampling techniques to accurately measure the true RMS of voltage current power and other parameters of three-phase power equipment and the accuracy is 0.2.
● The instrument can replace the same level of nine pointer meter is the ideal replacement of traditional electric power meter.
