2. The Model 3015A Digital Insulation
Resistance Tester
The Model 3015A Digital Insulation Resistance Tester is a lightweight and portable megohmmeter
designed for high voltage insulation resistance tests. You can use this device to measure the insulation
resistance of insulating materials, motors, cables, transformers, and electrical installations. This device
gives you real-time results in ohms or megohms that can be stored or exported for future analysis.
It has strong anti-interference and is indispensable for the following:
• Electrical systems
• Electric telecommunications
• Substation testing applications
• Metrology and computer rooms
• Oil fields
• Industrial enterprises
• Electromechanical installation and maintenance
The Model 3015A Digital Insulation Resistance Tester is an industrial tester designed to provide
years of dependable service. This device is powered by an advanced lithium-ion battery and can perform
hundreds of insulation resistance tests from a single charge. It has selectable functions that are
programmable for measuring DC voltage, AC voltage, DC current, insulation resistance (IR), capacitance,
polarization index (PI), and dielectric absorption ratio (DAR).
The insulation resistance (IR) quality of electrical systems deteriorates over time due to environmental
conditions and the presence of electrical and mechanical stress. The performance and life of electrical
systems depend on the insulation conditions. That is why it is vital to check the IR of electrical systems
periodically. The Model 3015A Digital Insulation Resistance Tester generates a high voltage across
the insulator to measure resistance. It safeguards electrical systems from abrupt current leakage in
wires that lead to accidental damage, blown circuits, or electrical shocks.
2.1 Overview
2.2 How the Model 3015A Digital Insulation Resistance
Tester works

5
The Model 3015A Digital Insulation Resistance Tester generates a high voltage (V) that creates
electron flow across the insulator. It measures the flowing current (I) and calculates the insulation
resistance value (R) according to the formula, Resistance = Voltage/Current (R=V/I).
