What tool is used to test the insulation integrity of electrical equipment?

• A. Multimeter
• B. Insulation resistance tester
• C. Oscilloscope
• D. Power quality analyzer

Answer: (B)

The insulation resistance tester is the appropriate tool to test the insulation integrity of electrical equipment because it specifically measures the resistance provided by insulation materials. By applying a known voltage, typically between 250V and 1000V, the tester evaluates how well the insulation can resist electric current, which is essential to ensuring safety and functionality in biomedical equipment. This measurement is critical for determining whether the insulation is adequate to prevent electrical leakage or short circuits, which can pose significant risks in a medical setting. Other tools, such as a multimeter, primarily measure voltage, current, and basic resistance but are not specialized for assessing insulation integrity under high voltage conditions. An oscilloscope is used for observing the changing signal voltages in electronic components and circuits rather than for insulation testing. A power quality analyzer assesses the quality of the electrical power being delivered to equipment but does not directly test the insulation of those devices. Thus, the insulation resistance tester is uniquely suited for this specific purpose.
