What is Fluxmeter？DefinitionA flux meter is an instrument designed to measure the magnetic flux of a permanent magnet. It represents an advanced iteration of the ballistic galvanometer, boasting certain advantages. Specifically, the flux meter features low controlling torque and significant electromagnetic damping.Construction of Flux MeterThe construction of the flux meter is depicted in the figure below. The flux meter incorporates a coil that is freely suspended using a spring and a single si

Electrical fault testing is a critical component of power system maintenance and management, aimed at detecting and preventing potential faults early to ensure the stability and reliability of the electrical grid. By identifying and addressing issues before they escalate, electrical fault testing helps prevent large-scale power outages. Below are the key measures and strategies involved in this process:1. Regular Preventive Maintenance and Testing Preventive Maintenance: Regularly inspect and ma

What is a Contact Resistance Meter?A contact resistance meter is a specialized instrument designed to measure the contact resistance between electrical connection points, such as terminals, plugs, sockets, switch contacts, and relay contacts. Contact resistance refers to the resistance formed at the interface where two conductive surfaces meet. While typically much smaller than the resistance of the conductors themselves, excessive contact resistance can lead to poor current flow, overheating, a
