LS-IR1515Y High-Voltage Insulation Resistance Tester

LS-IR1515Y High-Voltage Insulation Resistance Tester, also known as a high-voltage megohmmeter or high-voltage insulation resistance meter, is engineered to IEC 60270 standards with comprehensive testing functions for various insulation resistance parameters, user-configurable test voltage settings, and superior electromagnetic interference immunity. This instrument demonstrates exceptional performance in high-interference environments such as electrical substations and applications with significant distributed capacitance. The tester incorporates a true-color capacitive touchscreen interface that simultaneously displays all measurement data and battery status with high visibility. The control system combines rotary selector switches with dedicated function buttons to facilitate intuitive operation without requiring memorization of complex procedures. Activation of the integrated “HELP” function provides immediate operational guidance directly on the display.

This instrument is specifically designed for insulation resistance testing of high-capacity electrical equipment, high-voltage apparatus, and transmission lines in environments with substantial induced electrical interference. It serves as an essential testing instrument for power utility departments, telecommunications infrastructure, meteorological facilities, data centers, petroleum operations, electromechanical installation and maintenance teams, and industrial enterprises. The integrated test timer automatically records measurement duration and stores results with precise date and time stamps. Historical test data can be reviewed directly through the touchscreen interface. The fully isolated USB interface and Bluetooth communication module enable secure data transfer to personal computers or mobile devices for subsequent analysis and documentation.

The tester is supplied with double-insulated, shielded test leads, and the high-voltage probe features interchangeable alligator clips and hook attachments to accommodate diverse testing configurations. The instrument employs a robust dual-layer enclosure construction with an IP65-rated external housing that provides protection against dust ingress and water jets, ensuring reliable operation in demanding field conditions.
