Can anyone help me with SCADA system.I want to know how many blocks of data can be transffered in one message.can it be less than 16 blocks? Also can analog as well as digital values within the same message ?and also whether different analog or digital values such as voltage,energy etc can be...
Hello,
Can anyone help me to find out the rated current/locked rotor current & load factor of a 15KW motor which is connected to 415V ac.Estimated full load current & maximum demand are 26Amps.Load diversification=.06.Thanks in advance.
According to our expirience not needed any grading of overcurrent protection of zigzag with other overcurrent relays.
Actually phase current of zigzag very very small.
So as far as overcurrent relay grading is considered,all other relays should be graded over o/c relay of zigzag transformer.Is...
When grading the overcurrent relay of an earthing transformer(zig zag) with other overcurrent relays downstream,what is the criterion to be followed?is it to be made more sensitive than others i.e it should trip before other overcurrent relays dowstream or it should be treated as ordinary...
