d) EXAMPLE
A composite curve can be created from the GE_111 standard with MRT = 200 ms and HCT initially disabled and then
enabled at eight (8) times pickup with an operating time of 30 ms. At approximately four (4) times pickup, the curve operat-
ing time is equal to the MRT and from then onwards the operating time remains at 200 ms (see below).
Figure 5–23: COMPOSITE RECLOSER CURVE WITH HCT DISABLED
With the HCT feature enabled, the operating time reduces to 30 ms for pickup multiples exceeding 8 times pickup.
Figure 5–24: COMPOSITE RECLOSER CURVE WITH HCT ENABLED
Configuring a composite curve with an increase in operating time at increased pickup multiples is not allowed. If this
is attempted, the EnerVista UR Setup software generates an error message and discards the proposed changes.
e) STANDARD RECLOSER CURVES
The standard recloser curves available for the L60 are displayed in the following graphs.
