Relay protection sensitivity is too high
Choosing this value too high reduces protection. Determine the maximum load imbalance current. Check transformer magnetizing current and inrush characteristics. One of the main requirements to relay protection is the sensitivity requirement, which implies consistent tripping during the short circuit (s c) events in the protected zone. The sensitivity should be sufficient to ensure reliable protec-tion during s c at the end of its specified zone under. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. Defining Performance The performance of a relay element or relaying scheme is described using the terms selectivity, speed, and sensitivity. Selectivity is a measure of how well a relay element can differentiate between an in-zone and an out-of-zone. Proper Earth Fault Relay Sensitivity Settings play a crucial role in ensuring reliable protection for electrical systems.

What does it mean if the optical module power is too high
Overloading of optical power, also known as saturated optical power, refers to the maximum allowable optical power that the optical module can withstand without causing signal “explosion” and subsequent data loss. The unit of measurement for overload optical power is dBm. When the optical modules at both ends of the link work normally, the transmit optical power is within a certain range, which can be learned by checking the corresponding product datasheet or reading the module threshold on the switch. If it still does not work, change the module. Even minor deviations—whether too high, too low, or unstable—can impact signal integrity, trigger service alarms, or interrupt traffic on DWDM, OTN, or long-haul optical line systems.

Why is the distance of the KVM switch not high
KVM switches typically have a limited range, and the distance between the switch and the computers can affect the quality of the video signal. If the distance is too great, the video signal may degrade, resulting in a poor quality image. or, and mouse (KVM station) and a computer. Since PS/2 and USB keyboard and mouse protocols are only designed to run at a distance of about 16-33 feet, and digital video signal quality is typically starting to deteriorate beyond about the same cable length (depending on the type of cable and. A KVM switch is a device that manages multiple video and peripheral signals, enabling access via a single screen, keyboard, and mouse—or, in reverse, through a reverse KVM switch. This technology allows operators to efficiently control multiple data or AV sources and is compatible with any. A KVM switch (with KVM being an abbreviation for "keyboard, video, and mouse") is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, video monitors, and mouse. Typically, it is a set of transmitter and receiver appliances. Some KVM manufacturers such as Raritan and StarTech.

How to solve the problem of high light decay in cold-joint components
Are you struggling with unreliable connections on your PCB due to cold solder joints? Hot air rework is a powerful technique to fix these issues and restore your board's functionality. A cold solder joint forms when the solder does not properly bond the component lead to the pad—typically due to inadequate heat, oxidation, or poor technique. While these joints may look acceptable at first glance, they can become problematic over time, especially when exposed to vibration, thermal. This guide explains what a cold solder joint is, what it looks like, why it happens, and how to reliably identify, fix, and prevent it.
