ywshaikh asked What kind of motor protection relay should I use?
I'm an intern, so I could use some help here. My boss has given me a few choices between some Schweitzer relays, the SEL-701, SEL 749M, and the SEL-710. We have 4160V, 3 phase, feeding 3 motors; one rated at 1200 HP and the other 2 at 4000HP. This is for a compressor station on a gas pipeline. If anyone could let me know what type of protection would be necessary I'd appreciate it (IEEE std. numbers, I'm confused as to which ones would be necessary or not) Well I came up with a drawing for it and it seemed fine to me, but he said that there were some unnecessary devices that I had put in there. So that's what is confusing me. Thanks for the help though guys, I think I should be able to get this done.
And got the following answer:
Use SEL-710 Motor Protection Realy. The sophisticated protection relay is necessary in your case because the motors you protect are large and may be expensive to repair. From my 25 years experience in motor operations, ordinary thermal overload relays sometimes don`trip motoers on time. Overheating caused by under or overfrequency in power supply are not detected.
The sel-701 motor protection relay function very properly with distinct applications which are distinct to power distribution and protection. The relays come with wide adjustment ranges using a scale that is definitely easy to study either in three or 4 digits according to the model. These sel-701 motor protection relay help in increasing the flexibility with the applications, decrease the general energy and maintenance charges. There are relays which are made use of for basic purposes which are available in reputable designs with quick replacement solutions. And you will find models which can be utilized for industrial applications and heavier duty applications that function on massive loads. These goods are produced to meet the lifetime industrial manage requirements in the applications.
Their newest products would be the Time counter, Timer Delay, sel-701 motor protection relay, Swift Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and different other individuals. The site offers a detailed description of every single model in several categories of sel-701 motor protection relay couplings and sensors. These products are particularly valuable for high-risk applications. The sel-701 motor protection relay are also available with features like several timing ranges and functions. The enterprise is currently seeking agents and dealers who can market and sell their factory produced solutions. They are usually on a lookout for developing new and more trusted merchandise based on the wants and requirements of the business.
