HZ-IV Transformer Low Voltage Short Circuit Impedance Test Equipment

HZ-IV Transformer Low Voltage Short Circuit Impedance Test Equipment

The Transformer LV Short-Circuit Impedance Tester operates without an external voltage regulator and uses a primary connection method. It automatically performs three-phase testing and calculates impedance error percentages upon parameter entry, delivering clear and intuitive results. Designed for on-site use, this portable device enables rapid detection of winding deformation in transformers.

Characteristics

Automatic Three-Phase Testing: The tester is supplied with AC 220 V low-voltage power to automatically provide current for the AB, BC, and CA high-voltage windings of the transformer. It collects data simultaneously and automatically calculates the impedance error percentage, delivering intuitive test results.

Primary Connection Mode: The tester completes three-phase testing automatically in the primary connection mode rather than the inversed connection with the testing wire.

Flexible Testing Modes: The tester allows either single-phase or three-phase testing, both manually and automatically.

Adaptive Current Limiting: The tester achieves output current limiting applicable to test items with any impedance value.

No External Regulator Required: The test item can be measured without an external voltage regulator.

Zero-Sequence Impedance Measurement: The tester is capable of measuring zero-sequence impedance.

Inductance Measurement: The tester is capable of measuring inductance.

Large LCD Display with Chinese Menu: The tester features a large LCD display with a Chinese-language menu. Operation is facilitated by on-screen notes and prompts.

Printing, Storage & Portability: The tester enables printing and data storage, and is characterized by high testing accuracy, high automation, compact size, and light weight.
