Product Introduction
The LD-514 Insulation Resistance Tester can output up to 10kV, with a short-circuit current of up to 5mA and a range of up to 2000GΩ. It overcomes the drawbacks of conventional megohmmeters, such as low short-circuit current, inaccurate testing, and susceptibility to interference.
When testing the insulation resistance of high-capacity electrical equipment, the insulation resistance value is related to the duration of voltage application; the longer the voltage is applied, the higher the insulation resistance, a phenomenon known as the insulation absorption effect. To understand the insulation performance of the tested item, it is necessary to first conduct absorption ratio and polarization index tests, providing a safety guarantee for subsequent insulation performance tests such as leakage, dielectric loss, and partial discharge. The LD-514 Insulation Resistance Tester, by conducting insulation, absorption ratio, and polarization index tests on electrical equipment, provides an accurate preliminary judgment for a series of insulation tests. It is a new type of intelligent instrument and the preferred choice for testers.
The LD-514 Insulation Resistance Tester is primarily used for testing the insulation resistance values and absorption ratio, as well as the polarization index of high-voltage electrical equipment. This instrument features an LCD large-screen display with gray and white backlight, data storage, data review, alarm, and automatic shutdown functions. It also has the capability to measure DC voltage, AC voltage absorption ratio, and polarization index. The unit is aesthetically pleasing, with a wide measurement range, high resolution, easy operation, and convenient portability. It is accurate, reliable, and has stable performance with strong anti-interference capabilities. Additionally, it features shockproof, dustproof, and moisture-proof structures, making it an indispensable instrument commonly used in telecommunications, power, meteorology, data centers, oil fields, electrical and mechanical installations and maintenance, and industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring the resistance values of various insulation materials, as well as the insulation resistance of transformers, motors, cables, and electrical equipment.
