Transformer Low-Voltage Short-Circuit Impedance Tester Product Introduction

ED0207The No-Load Current Tester, also known as the Transformer Low-Voltage Short-Circuit Impedance Tester, is used for measuring transformer no-load and load parameters. The Transformer Low-Voltage Short-Circuit Impedance Tester can perform precise measurements on a series of parameters, including no-load current, no-load losses, short-circuit losses, and impedance voltage, for various transformers.

ED0207The Transformer Low Voltage Short-Circuit Impedance Tester is designed for precise measurement of a range of parameters for various transformers, including no-load current, no-load loss, short-circuit loss, and impedance voltage.

 ED0207The Transformer Low Voltage Short Circuit Impedance Tester is equipped with main functions including: B&W screen display, automatic waveform distortion correction, temperature calibration, voltage calibration (no-load test under non-rated voltage), and current calibration (short-circuit test under non-rated current conditions, using rated current values).20%-70%Short-circuit test additional loss correction: personnel only need to input the correction index tester based on the transformer type, and the corrected results will be automatically calculated.

ED0207Transformer Low-Voltage Short-Circuit Impedance Tester(Monochrome)The device allows for the external connection of current and voltage transformers to expand the measurement range, with the capability to measure voltages as high as750VAuto-switching, large-screen display, and touch buttons for simplified operation make this maintenance and testing instrument an essential tool for transformer manufacturers and power maintenance companies.

ED0207The Type Transformer Low Voltage Short Circuit Impedance Tester is primarily used for low voltage short circuit impedance testing during the factory production, major overhaul, pre-commissioning, and handover tests of power transformers (single-phase or three-phase).

The principle involves short-circuit impedance testing of the power transformer on-site.%The test compares the values with the label or factory settings, enabling the detection of defects such as winding displacement and deformation caused by severe fault currents during transportation, installation, and operation after factory testing.

ED0207The Type Transformer Low Voltage Short Circuit Impedance Tester is easy to operate and provides highly intuitive test results, making it a rapid instrument for on-site testing of transformer winding deformation.
