SCADA ready field test switch
A monitored SCADA Ready Field Test (FT) Switch is disclosed. The monitored switch relates to the incorporation of a monitoring switch for each switch unit in a FT switch to monitor the position of the corresponding switch unit and the FT switch, generally.
1. A field test switch comprising:
a plurality of independent relay switches wherein selected ones of said relay switches are organized to cooperatively operate with each other;
a monitoring switch associated with each of said relay switches, said relay switches effecting closure of said associated monitoring switch when in a first position, wherein said engaged monitoring switch enables a current to pass therethrough; and
an output associated with a corresponding monitoring switch, said output being provided to an external device, remotely indicating whether said monitoring switch is in an engaged position.
2. The field test switch of claim 1 , wherein said monitoring switches are connected in series.
3. The field test switch of claim 1 , wherein said monitoring switches are connected in parallel.
4. The field test switch of claim 1 , wherein said output is sensed locally to the FT switch.
5. The field test switch of claim 1 , further comprising:
a network interface for transmitting said output via a network.
6. The field test switch of claim 5 , wherein said network is selected from the group consisting of: wired and wireless.
7. The field test switch of claim 1 , further comprising: an indicator associated with each of said monitoring switches.
8. The field test switch of claim 7 , wherein said indicator is at least one LED, said LED being associated with one of the positions of said monitoring switch.
9. A monitoring assembly for an FT switch, said FT switch comprising a plurality of individual blade switches, said assembly comprising:
a momentary contact switch associated with each of the individual blade switches, said momentary contact switch providing an output indicative of a position of said contact switch.
10. The assembly of claim 9 , wherein said output represents a first indication when a corresponding blade switch is in a first position and represents a second indication when said corresponding blade switch is in a second position.
11. The assembly of claim 9 , wherein said output of each momentary contact switch is connected in series.
12. The assembly of claim 9 , wherein said output of each momentary contact is connected in parallel.
