About the 350-L-P5-G5-H-E-E-N-M-1E-D-N

Equipped with a drawout case design the 350-L-P5-G5-H-E-E-N-M-1E-D-N relay has a standard five-ampere ground current input. Prior to connecting this relay to the ground, it should be taken into account that the relay will calculate the residual current from the gross total of the three current phasors. The input associated with this relay, the ground current input, will be used in concurrence with the Zero Sequence CT as a source or potentially in the neutral of the wye-connected source currents. The ground current does have the possibility of polarizing the neutral directional element. 

According to the second character of the order code on this relay the LEDs are programmable with the language on the 350-L-P5-G5-H-E-E-N-M-1E-D-N relay being English. There are four named LEDs which are, alarm, trip, in service, and trouble; there are eight other LEDs which are simply labeled one through eight. There are different colors associated with the LEDs, LEDs five through eight are green/orange/red and are all programmable in not only color but in the source signal. 

Twenty-five protection setpoints are available on the 350-L-P5-G5-H-E-E-N-M-1E-D-N relay which includes VT fuse fail, sensitive ground directional, phase timed overcurrent, and many more. The full list of the protection setpoints can be found on pages fifty-eight and fifty-nine in chapter six. All of the information for the voltage elements current elements, VT fuse fail, and thermal models will be found on pages fifty-eight through one-hundred and twenty-eight of chapter six of the GEK-113507T 350 Feeder Protection System Manual.
