Nice teaching,can understand simply🙏
Your welcome 🙏
Bahut badiya sir 💓💓
very nicely explained
Excellent explanation
Nice work
thank you you are A great man
Please Make video on line interactive ups.
thank u bro
Your welcome
Sir there are two types of offline UPS..
Were they covered in this??
Bro can u make a video of line interactive ups
You're saying that transfer time is 5 ms. My question is, during the change-over the inverter doesn't have any inertia in energization? Unless it was in stand-by function during normal operation.
It has inertia in energization and job of engineers is to reduce this time. It will improve life of UPS
Good
What are the advantages of online ups???
Continuous Power Supply: Online UPS provides continuous power to connected devices without any interruption, even during power outages. It has a built-in battery that supplies power instantly, ensuring seamless operation of critical equipment.
Voltage Regulation: Online UPSs regulate the voltage supplied to connected devices, providing a stable and clean power output. They correct voltage fluctuations, spikes, and sags, protecting sensitive equipment from potential damage caused by inconsistent power quality.
Isolation from Utility Power Issues: Online UPS systems isolate connected devices from utility power problems, such as surges, voltage fluctuations, frequency variations, and harmonics. The UPS draws power from the utility, conditions it, and supplies it to the equipment, shielding them from potential electrical disturbances.
High Level of Protection: Online UPS offers a high level of protection against power anomalies, including power surges, voltage transients, and electrical noise. It provides robust safeguarding for sensitive and critical equipment, such as servers, data centers, telecommunications equipment, medical devices, and industrial machinery.
Seamless Transfer Time: In the event of a power outage or fluctuation, online UPS systems provide an immediate and seamless transition to battery power. The transfer time is typically zero or close to zero, ensuring uninterrupted power to connected devices and preventing any data loss or equipment malfunction.
Scalability and Flexibility: Online UPS units come in various sizes and capacities, allowing for scalability based on the power requirements of different applications. They can be easily configured and expanded to accommodate additional equipment, making them flexible and adaptable to changing needs.
Battery Management: Online UPS systems continuously monitor and manage the battery charging process. They provide battery health information, perform regular self-tests, and ensure that the batteries are in optimal condition. This proactive approach enhances the reliability and longevity of the UPS system.
Remote Monitoring and Management: Many online UPS models offer remote monitoring and management capabilities. Users can monitor the UPS status, battery health, load levels, and other parameters from a centralized management console or through network connectivity. This feature enables proactive maintenance, troubleshooting, and efficient management of the UPS infrastructure.
My offline ups doesnt give output even when MAIN IS ON. What is the fault??? Please help frontech electra 725 model
Hi Sir what is line interactive ups and where all three types of ups used that is online and offline and line interactive??
In off line ups , what will happen when ups fails ??
Will it work like on line ups ??
great
How the switching takes place?
Based on input power ON/OFF
How about from battery mccb breaker its off and from the inverter going two battery its on if make me On this one sir they have problem our no,bcuz the battery no supply going two inveter bit the normal power its on running,what this one sir for back up only, bcuz one ups its work and have power from battery two inverter
Plz Make video on CVT (capitor Voltage transformer)
sir why we use capacitor in ups??
sir, why it takes 5ms time ?
Due to switching
But how to static switch on off?
It's manually done or any auto system or any relay is placed
Bss naam btadegiyea apna sir shyed mai aap ke aawaz pehchaan rhaa hu
Hitesh Dholakiya
Sir please in hindi
You are school teacher not engineer
