Electrical fault detection is the process of identifying failures in an electrical system. These failures can range from minor disruptions to catastrophic events that damage equipment and injure people. Early and accurate detection is essential to minimize consequences and speed recovery.

Why Analog Meters Remain Relevant in Modern Industry
An analog meter is an electromechanical instrument that displays electrical quantities—such as voltage, current, or power—using a physical pointer that moves across a calibrated scale. Unlike digital meters that show numerical values, analog meters provide continuous visual feedback through needle movement. (more...)

Use a megohmmeter to measure insulation resistance in the field (non-destructive, trend monitoring). Use a hipot (dielectric withstand) tester to verify insulation breakdown thresholds in manufacturing or safety tests. Choose based on your use case, voltage needs, and test objectives. (more...)

The digital multimeter is one of the most widely used test instruments. A handheld DMM typically has 3½ or 4½ digit resolution and at least 3, but sometimes more than 10 functions (DCV, ACV, Ω, DCA, ACA, Hz, duty cycle, capacitance, continuity, diode test, etc). Newer meters include many features to increase safety, (more...)
