Just wondering which terminal emulator you use in order to write information to your relays (SEL's) during testing with macros? I am well aware there are several out there but i am looking for ease of use! all of a sudden my emulator wants to bounce baud rates around on me and was looking for a...
Has anyone had issues with the SEL 3332. I am currently installing an SEL 3332 at an electrical substation and I when I change status on a device the SEL protocol picks up the 1 bit change however it does not translate it to the CDC protocol?
I am currently working with a 2411 communicating...
I currently have a 250VDC battery which has multiple full positive grounds on it. I have pulled all the dc fuses one at a time and the dc potential on the ground still remains. I have been notified that this ground has been present for some time now and in my opinion other grounds have also...
Has anyone run across any really good macro builders for Doble's ProTest (preferably for SEL Relays)? I recently tried a beta version and really liked the results for a relay which was tested, however the program was still in its initial phases and a majority of (SEL) relays were not supported...

I am wondering what benefit would you get from running a 1hp motor at 208vac vs 115vac. A customer has been told it would be cheaper to run the motor off of 208vac. The customer is having no problem running the motor off of 115.
two questions
Will the motor run cooler?
Would it ultimately be...
I have been blessed with my newest project to design a system. There are several controls in my new process all having rs-232 connections approximately 9 of them.Mainly temperature flow and pressure. I am looking for a low cost, reliable, easily operational SCADA system (I am guessing) for data...
I am using a temperature controller in order to control some heating tapes. The output of the temp control is 5 volts when I hooked it up to the input of a SSR 3-32V the output of thetemp control drops to @ 1V if I leave the volt meter accross the input the voltage rises to an acceptable level...
I am currently experiencing a problem with my Laboratory reactor tube. It has been breaking more often recently. It is made of an extruded alumina approx 2.25 inch OD 2.0 ID. The temperatures the tube is experiencing is 1200-1400C. Are there any types of coatings which could provide further...
I am dealing with AlCh3 and alot of my surrounding supplies, materials and my feed system is corroding. I was wondering if anyone out there knows of a company which can supply a sacrificial anodes to ensure the life cycle of at least my feed system.
Thanks

I would like to be able to regulate the amount of free flowing air through some pipework. I am using a vacuum in order to draw the air in. Does anyone know of a company which sells a regulator which can work with ambient room pressures and regulate/control fairly small flows 5-30 Lpm cost...
Does anyone know of a company which can plasma coat inside a two inch ID pipe as they do in turbine coating. The pipe is approx 54 inches long, hastalloy X material and will be heated up to 1700 C I am currently using extruded alumina tube but it is very fragile. I would like to switch to a high...
