How is the relay protection from Panama Electric
Each relay provides the following functions: 87L protection that uses phase (87LP), negative-sequence (87LQ), and zero-sequence (87LG) differential elements to provide phase and ground fault protection. A practical guide to how protective relays detect faults, trip circuit breakers, coordinate protection zones, and improve power system reliability. Protective relays and devices have been developed over 100 years ago to provide “last line” of defense for the electrical systems. P&C System Description The P&C system uses multifunction relays with communications and programmable logic. It has a set of input terminals for one or more control signals, and a set of operating contact terminals.

How to break a Revit cable tray
If you want to remove the segment of the cable tray between selected points, on the Options Bar, select Delete Inner Segment. Aha - My Take is that the cable trays on either side are at slightly different elevations - and its mucking this up (but dont know why it should!) Has this been traced over an AutoCAD drawing? Everything seems slightly out. (and I dont know what this rogue image is below this line, there should. I am trying to create a script that will insert a cable tray union at a given point along the cable tray. Yes, I understand that Fabrication has this but when coordinating it is much easier moving and adjusting Revit MEP parts then run the Dynamo script to speed things up. Above lights, below ducts — coordinate with ceiling plenum. Tees, crosses, and reducers handle every direction change. Review the basics of placing cable tray, add vertical cable tray, and place cable tray and fittings. Is it possible to connect 2 cabletrays with a "branch piece (left picture)" instead of a "tee (right picture)". I would like to ajust the "Type properties -> Fittings -> Tee" with the branch family, but can't get it accomplished.
