In order to implement these schemes, it is not necessary to set any setting in the element. Internal functions are always
operative and provide the following logic operands:
Table 5-87: Supervision logic operands
A continuity failure is detected in a circuit when both voltage detectors (Va and Vb) detect lack of voltage during more than
500 ms. This function is not influenced by the breaker status.
These operands can be associated with internal signals (virtual outputs), LEDs or element outputs, to issue alarm signals or
to block elements, for example for blocking the Breaker close if an anomaly is detected in the trip circuit.
Available schemes are as follows:
1.
Without supervision
2.
With current supervision (with seal-in)
3.
With simple voltage supervision
4.
With double voltage supervision
5.
With current and simple voltage supervision (with seal-in)
6.
With current and double voltage supervision (with seal-in)
7.
With current and double voltage supervision (with seal-in) and serial resistor in voltage monitors.
The following subsections describe the different types of connection to create each supervision scheme in an easy way. As
the supervision circuits are identical, only the first group connection examples are described, being also applicable to the
second group.
In order to assure a high isolation level between groups, the digital inputs for supervision have been located in a
symmetrical basis. That is to optimize the isolation between groups that can be connected to different batteries, and
therefore requiring a greater distance between circuits.
