Goblin – Operational Manual
TRINITY
[37]
response times as outlined above for closing of relays also applies to opening of
relays. Thus, the relay will open at 380 only if the parameter falls below 380 and
remains so for 1 minute (2 seconds in case of Demand).
If all four relays are programmed to close on Demand and different values for closing
and opening are set by the user, GOBLIN can be used effectively as a Maximum
Demand Controller with four relay contacts!
Goblin as a Load Manager / Demand Management
Each relay can be programmed separately to generate alarm on a specific
parameter with its specific value. The value at which it should open is also
programmable. Thus, user could have the first relay programmed to close when the
avg. Voltage exceeds certain value, second when the Avg. Amps exceeds some
level, third for KW, or KVAR or PF or Demand and so on.
This allows the user to deploy GOBLIN as a true LOAD manager, to generate alarm /
trip signals for four different conditions!
KW=17.27
KVA=21.61
KVAR=13.07
PF=0.796
