How to measure the temperature of the busbar of a high-voltage switchgear

How to measure the temperature of the busbar of a high-voltage switchgear

Non-contact infrared sensors continuously monitor busbar temperature from a safe distance within cabinets, avoiding physical contact or complex insulation requirements. Temperature monitoring in high-voltage busbar systems is vital for preventing faults, yet difficult due to electrical hazards, limited accessibility in switchgear cabinets, and interference risks in traditional contact-based methods. Temperature rise testing is one of the recommendations of IEC 61439; our system for monitoring switchgear and busbars is easily integrated with new installations or retrofitted to existing infrastructure. Busbar (copper row) lap surface is the "throat" part of the power transmission and distribution system, and its contact state directly determines the efficiency and safety of power transmission. In this paper, we analyze the micro-mechanism and evolution of busbar lap surface heating, and explain. Due to busbars conducting high currents, small rises in temperature can be indicative of faults.

How to handle indoor fiber optic cable bends

How to handle indoor fiber optic cable bends

After pulling cable, excess cable must be stored, usually in manholes or handholes. This article provides a practical, installation-focused guide to fiber bend radius, including definitions, standards, common mistakes, and best practices. Fiber optic cable bend radius is a critical mechanical parameter that determines how sharply a cable can be bent without risking microbending, macrobending, signal loss, or long-term structural fatigue. Proper bend radius control ensures the integrity of optical performance and protects the glass. However, these slim cables often need to twist and turn during infrastructure builds and maintenance.

How to handle a loose fiber optic cable connection

How to handle a loose fiber optic cable connection

Start with the simplest, fastest checks (visual inspection, cleaning, cable routing) and only move to instrumentation (power meter, VFL, OTDR) when those steps don't clear the fault. While a cut or damaged fiber optic cable can temporarily take your network down, it is possible to quickly fix the cable with the right tools. Fiber optic troubleshooting is an essential skill for network administrators, technicians, and engineers responsible for maintaining and repairing fiber optic systems. With a structured approach and the right tools, you can quickly identify faults, restore connection quality, and.

How to test if a fiber optic splitter has network connectivity

How to test if a fiber optic splitter has network connectivity

Testing a splitter or other passive fiber optic devices like switches is little different from testing a patchcord or cable plant using the two industry standard tests, OFSTP-14 for double-ended loss (connectors on both ends) or FOTP-171 for single-ended testing. Although both optical splitters and patch cords are tested using an optical power meter and light source, there are some differences in testing them. What are Optical Splitters? The fiber optic splitter is a device used in fiber optic networks to divide a single optical signal into multiple signals. This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance.
