Time discrimination
This type of discrimination is an evolution from the previous one. The setting
strategy is therefore based on progressively increasing the current thresholds
and the time delays for tripping the protective devices as we come closer to the
power supply source. As in the case of current discrimination, the study is
based on a comparison of the time-current tripping curves of the protective
devices.
This type of coordination:
• is easy to study and implement;
• is relatively inexpensive;
• enables to achieve even high discrimination levels, depending on the Icw of
the upstream device;
• allows a redundancy of the protective functions and can send valid information
to the control system,
but has the following disadvantages:
• the tripping times and the energy levels that the protective devices (especially
those closer to the sources) let through are high, with obvious problems
concerning safety and damage to the components even in zones unaffected
by the fault;
