  Electrical systems play a crucial role in our modern lives, powering everything from homes to industries. To ensure the safety and reliability of these systems, it is essential to regularly inspect and test the insulation resistance of electrical components. This is where an   Insulation Resistance Tester   becomes indispensable. What is an Insulation Resistance Tester? An Insulation Resistance Tester (IRT) is a specialized instrument designed to measure the resistance offered by the insulation material between the conductive parts of electrical equipment. In simpler terms, it evaluates the effectiveness of insulation in preventing current leakage in electrical systems. How Does It Work? The IRT applies a high voltage to the insulation under test and measures the resulting current flow. The principle behind this lies in Ohm's Law (V=IR), where voltage (V) is applied, and the current (I) and resistance (R) are measured. By knowing the applied voltage and the current flow...
