Description

Mastering High-Voltage Insulation with Precision

In the demanding world of high-voltage electrical systems, the integrity of insulation is the single most critical factor for ensuring safety, reliability, and operational continuity. From power transformers and switchgear to high-voltage cables and industrial motors, the insulation of these components acts as a protective barrier, preventing dangerous current leakage and short circuits. As systems age or are exposed to environmental stresses, this insulation can degrade, creating silent, invisible risks that can lead to catastrophic failures, equipment damage, and serious safety hazards. A high-voltage insulation resistance tester is the indispensable tool for detecting these issues before they escalate. Our featured product is an exceptional instrument, designed to perform these essential diagnostics with a level of precision and power that sets it apart from conventional testers. With a maximum test voltage of 12kV and the ability to measure resistance up to an astounding 35TΩ, this device is built for the most challenging and critical high-voltage applications. Its advanced capabilities provide professionals with the confidence to assess the health of their electrical systems accurately. This isn’t just a meter; it’s a comprehensive diagnostic solution that enables proactive maintenance, helps prevent unscheduled downtime, and ensures a safer working environment.

Advanced Diagnostics with Unparalleled Test Power

This insulation resistance tester is a technological powerhouse, offering a suite of features that provide advanced diagnostics for complex electrical systems. The ability to perform a test with a maximum voltage of 12kV and measure resistance up to a staggering 35TΩ is a game-changer. This high voltage capability allows for thorough testing of insulation on large, high-capacity equipment, revealing weaknesses that lower-voltage testers would miss. The maximum short-circuit current of 5mA is a crucial safety feature, ensuring that the test current is limited to a safe level, protecting both the user and the equipment under test. A standout feature is the graphic representation of the insulation resistance and leakage current versus time on a large display. This visual trend analysis is invaluable for diagnosing insulation health, as it allows technicians to observe the characteristic behavior of insulation over time. The display, complete with a bar graph and backlight, ensures that data is easy to read even in low-light conditions. The Print Screen function is another remarkable addition, enabling technicians to record up to 32 display screens for later analysis or reporting. This eliminates the need for manual transcription and ensures a permanent, accurate record of the test results. Furthermore, the device’s internal memory can store about 43,000 data points, providing an extensive data logging capability that is essential for long-term monitoring and trend analysis.

Tailored Testing with Variable Voltage Control

The flexibility of this insulation resistance tester is a key factor in its professional utility. It offers multiple fixed test voltages—500V, 1000V, 2500V, 5000V, 10000V, and 12000V—allowing technicians to choose the appropriate voltage for the equipment being tested. The device’s impressive maximum measurement values, ranging from 500GΩ at 500V to 35TΩ at 12000V, ensure that it can handle an enormous range of insulation conditions. The accuracy of these measurements is also exceptional, with a tolerance of ±5%rdg±3dgt for the primary measuring ranges and ±20%rdg for higher resistance values, which is still highly reliable for such a vast range. The device’s ability to precisely control the output voltage is a significant advantage, with selectable ranges from 50V to 12000V in fine steps. For example, the user can set the voltage from 50 to 600V in steps of 5V, or from 10100 to 12000V in steps of 100V. This level of granular control is crucial for performing specialized tests, such as step-voltage or dielectric absorption tests. The device also measures AC and DC voltage up to 600V, providing a comprehensive view of the circuit’s state before and after the insulation test. Furthermore, it can measure current from 5.00nA to 2.40mA and capacitance from 5.0nF to 50.0μF, making it a truly multi-functional diagnostic tool.

Critical Applications Across Diverse Industries

The powerful capabilities of this high-voltage insulation resistance tester make it an essential tool across a wide spectrum of industries. In the power generation and distribution sector, it is used to assess the insulation of critical assets like large power transformers, generators, and high-voltage transmission lines. Regular testing can detect early signs of moisture ingress or degradation in a transformer’s windings, preventing a potential failure that could lead to widespread power outages. Heavy industrial facilities rely on this device to maintain the integrity of their motors, switchgear, and control panels. These components are often subjected to high stress and contaminants, and routine insulation testing is key to preventing costly production downtime. The variable voltage capability is particularly useful for testing a variety of industrial equipment. In the rail and transportation industry, it is used to test the insulation of traction motors and electrical systems on trains. For telecommunications and data centers, where reliable power is paramount, the device is used to test the insulation of uninterruptible power supply (UPS) systems and backup generators. The device is also invaluable for research and development laboratories where new insulating materials and high-voltage components are being designed and tested. The data logging and graphic display features are perfect for conducting detailed material analysis and quality control.

The Engineering Behind Unwavering Reliability

The design and construction of this insulation resistance tester are a testament to its professional-grade engineering, built to withstand the rigors of field use. The device is housed in a robust case with an IP64 rating (with the lid closed), which signifies its high level of protection against dust ingress and splashing water. This makes it suitable for use in harsh outdoor environments and dusty industrial settings without compromising its performance. The ability to be operated from an internal rechargeable battery or from an AC line provides a high degree of operational flexibility. The rechargeable lead-acid battery provides a long continuous measuring time—approximately four hours with a load of 100MΩ at 12000V—ensuring that technicians can complete extensive testing without needing a power outlet. When a power source is available, the device can be connected to an AC line (100V to 240V, 50/60Hz) for continuous use and simultaneous charging. The device’s physical dimensions of 330 (L) × 410 (W) × 180 (D) mm and weight of approximately 9kg (including the battery and hard case) reflect its solid build quality and comprehensive internal components. It is a substantial, professional tool, not a lightweight consumer device. The included accessories, such as the Power cord (7170 or 7240), Earth cord (7224A), Guard cord (7225A), and various probes, are all of high quality and are designed to complement the device’s durability and functionality.
