So far by adjusting relay operating time, both of the factors to be adjusted. The adjustment of traveling distance of an electromechanical relay is commonly known as time setting. This adjustment is commonly known astime setting multiplier of relay. The time setting dial is calib...

This paper describes the Firefly algorithm for optimal time coordination of these relays. The algorithm has been implemented in MATLAB and tested on a radial ...
You then program the “upstream port” with the “downstream device” MAC and the “downstream port” with the “upstream device” (switch/router/server) MAC. And if you want to do it properly you need a multipole relay and control CCT on the ports so when the tech comes around to chec...
In the proposed approach three decision variables are considered for each relay; namely, the standard characteristic curve (SCC), Time Multiplier Setting (TMS) and maximum limit of the plug setting multiplier (PSM). The proposed mixed integer non-linear programing model is sol...
The Time Multiplier Setting (TMS) is used practically to provide time grading to the distribution systems. The Plug Setting (PS) provides for different pick up values for the relays to operate. However, the Inverse Definite Minimum Time relay operating time mathematical expression depends on both ...
