Advanced Insulation Testing with ZX2550 HV Tester

Insulation resistance testing is crucial for ensuring the safety and reliability of high-voltage electrical equipment such as transformers, generators, motors, and cables. The ZX2550 HV Insulation Resistance Tester stands out as a robust and versatile tool designed for such demanding applications. This article provides a technical overview of the ZX2550, highlighting its key features and performance indicators relevant to engineers and technicians.

Key Features

The ZX2550 incorporates several user-friendly and durable design elements:

1.Dual-Scale Display & Auto-Ranging: It features an easy-to-read display with a green upper scale and a red lower scale, complemented by an LED indicator. The auto-ranging capability automatically switches between scales, simplifying operation and reducing the potential for reading errors during measurements.

2.Robust Construction: Housed in a portable ABS plastic case, the instrument is compact, aesthetically pleasing, and offers strong resistance to electromagnetic interference. Its ultra-thin taut suspension meter ensures good shock resistance, making it suitable for use in various field conditions.

3.Flexible Power Options: The tester includes a built-in rechargeable battery and an AC charging module, providing flexibility for extended use in locations without immediate access to mains power.

Technical Specifications and Performance

The ZX2550 offers multiple test voltages, making it adaptable to a wide range of equipment insulation testing requirements. Its core technical indicators are summarized below:

Outside the specified accuracy ranges, the tolerance is ±10% of the reading. The output voltage accuracy is maintained within ±5% under standard conditions.

Comparison and Context

When compared to basic megohmmeters, the ZX2550's key advantages become clear:

1.Wider Application Range: With test voltages up to 10kV and a maximum measurement capability of 400 GΩ, it is suited for testing high-capacitance and high-resistance assets like long power cables and large generators, where lower-voltage testers are insufficient.

2.reliable data for predictive maintenance, a significant step up from general-purpose testers with wider tolerances.

3.Advanced Features: Optional capabilities such as Dielectric Absorption Ratio (DAR) and Polarization Index (PI) measurements, which are critical for advanced insulation condition assessment, are available, placing it above simpler pass/fail testers.

Environmental and Safety Specifications

The instrument operates reliably within a temperature range of -10°C to 40°C and up to 85% humidity. It boasts a high insulation impedance (>1GΩ) between its circuitry and case and can withstand 5000V AC for one minute, ensuring operator safety.

Conclusion：

The ZX2550 HV Insulation Resistance Tester is a comprehensive solution for maintenance and commissioning teams working with medium and high-voltage apparatus. Its combination of multiple test voltages, high measurement range, auto-ranging functionality, and robust design makes it a technically superior choice for accurate and reliable insulation resistance diagnostics in the field.
