HZ-3220A Transformer DC Resistance Meter Temperature Rising Tester

HZ-3220A Transformer DC Resistance Meter Temperature Rising Tester

The instrument applies a double constant current source design, with CPU-controlled charging and discharging sequences and comprehensive protection measures, making it highly suitable for temperature rise testing of transformers with significant differences between high and low voltage windings.

Performance Characteristics

1. The instrument features high output current (maximum output: 20 A) and a wide testing range (maximum: 2 kΩ), making it suitable for temperature rise testing and DC resistance measurement of all transformers rated 35 kV and below.
2. Perfect dual power supply design. Supports simultaneous and individual testing of high-voltage and low-voltage sides.
3. This instrument features protection and alarm functions for AC 380 V power supply misconnection, wire breakage, and arc-resistant protection, along with audible discharge alarm. Indication is clear, reducing misoperation. With a comprehensive protection circuit, reliability is strong.
4. Large color touchscreen for clear and legible data display.
5. Temperature rise testing is printed automatically according to the set time, and temperature rise data are stored for convenient recording.
6. The instrument is equipped with a perpetual calendar, 100 groups of conventional data storage, and result storage for 3 temperature rise tests. Data will not be lost after shutdown, facilitating review. A USB interface is provided for convenient data export to generate temperature rise curves.
7. The instrument is equipped with an RS485 communication interface; remote control measurement can be realized after installing the host computer operation and control software.
8. This instrument is equipped with temperature rise software, which can carry out data processing and generate temperature rise curves automatically.
