Technical Overview of the ZXJYD-IV Insulating Oil Breakdown Voltage Tester

The ZXJYD-IV Insulating Oil Breakdown Voltage Tester represents a dedicated instrument developed for accurately determining the dielectric breakdown strength of insulating oils. Engineered by our technical team through extensive research, field testing, and in strict accordance with international standards IEC 156 and ASTM methods (D877, D1816), this tester combines high precision, full digitalization, and automated operation to meet rigorous laboratory and field service requirements.

Development & Compliance
The instrument's design is grounded in standardized test methodologies, providing built-in procedures for IEC 156, ASTM D877, and ASTM D1816. This multi-standard compliance ensures reliable and comparable results across different regional and operational specifications. A custom test mode further offers flexibility for specialized user requirements.

Core Technical Features

1.Stable Control System: At its heart is a high-capacity single-chip microcomputer (MCU) that ensures stable and reliable control over the test sequence.

2.Enhanced Reliability: An integrated hardware watchdog circuit effectively prevents system crashes, guaranteeing uninterrupted operation.

3.Robust Test Cell: The key component—the test cell—is constructed from specially molded glass, eliminating risks of oil leakage and minimizing external interference during critical measurements.

4.Accurate Measurement Circuitry: A design featuring high-voltage terminal sampling directly feeds the signal to an Analog-to-Digital Converter (ADC). This approach minimizes errors typically introduced by intermediate analog circuits, yielding more precise and direct measurement results.

5.Comprehensive Protection: The instrument incorporates multiple protection mechanisms against overflow, overvoltage, and short-circuit conditions. These features contribute to its strong anti-interference capability and robust Electromagnetic Compatibility (EMC).

6.User-Centric Design: It features a clear, large LCD with Chinese character display for intuitive operation. Its portable structure facilitates easy transportation for use in both laboratory and on-site environments.
