Improper instrumentation grounding and shielding can cause measurement errors and degrade reliability in instrumentation and control systems. An understanding of these factors is essential for both system design and installation.
How Many Grounds?
The term ground is used in several ways. It can be a direct physical connection to the Earth, (more...)

Current transformers (CTs) are used in many applications that require current, power or energy monitoring. Examples include power generation, submetering, protective relaying, motor control, and machine fault detection. Selecting a current transformer involves picking the style, ratio, burden, accuracy and insulation to (more...)

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 Industry Today.
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...)
