This section details the EZ (“easy”) settings – the settings used to
perform traditional recloser control operations.

•
Curve Designations

EZ Settings Sheets (end of Settings section)
Curve Information
Fast and delay curves are available for phase and ground overcurrent
protection. These curves can be set with any of the numerous resident
curve choices:
•
Recloser Curves (see Table 6)
•
US Curves (see Table 7)
•
IEC Curves (see Table 7)
•
User-Programmable Curves (see Table 7)
The recloser curves in Table 6 show both the older electronic control
designation and the newer microprocessor-based control designation.
The recloser curves can be specified in a curve setting using either
designation. For example, a given traditional recloser curve has the
following two designations:
Older electronic control designation: A
Newer microprocessor-based control designation: 101
Traditional recloser curve A and curve 101 are the same curve – use
either designation in making curve settings in the SEL-351P.
Important:
This Quick-Start Installation
and User's Guide provides only
information applicable to the EZ
settings - settings associated
with traditional recloser control
operations.
