ProSight VK3015A & VK3015B Professional 1000V Insulation Resistance Testers
ProSight Professional High Accuracy 1000V Insulation Resistance Tester IP67 VK3015A and VK3015B are professional digital insulation resistance testers designed for electrical safety inspections, preventive maintenance, and equipment commissioning. They provide accurate insulation resistance measurements, AC/DC voltage testing, PI and DAR analysis, along with onboard data storage and USB communication. Their rugged portable design and user-friendly interface make them ideal for industrial, commercial, and utility maintenance professionals.
What is the Product?
The ProSight Professional High Accuracy 1000V Insulation Resistance Tester IP67 VK3015A and VK3015B are advanced digital insulation resistance testers developed to assess the insulation integrity of electrical equipment and installations. They are widely used for testing motors, transformers, generators, switchgear, power cables, control panels, and other high-voltage electrical systems.
These instruments help detect insulation deterioration, leakage current, moisture ingress, and aging insulation before equipment failures occur. In addition to insulation resistance testing, they offer AC/DC voltage measurement, Polarization Index (PI), Dielectric Absorption Ratio (DAR), internal memory, and USB communication for comprehensive testing and documentation.
How it Works
The tester applies a regulated DC test voltage to the insulation of the equipment under test and measures the resulting leakage current to calculate insulation resistance.
Higher resistance values indicate healthy insulation, while lower values may indicate contamination, moisture, aging, or insulation breakdown. The PI and DAR functions provide additional insight into insulation condition by evaluating resistance changes over time. Test results can be stored internally and transferred to a computer via the USB interface for record keeping and analysis.
