PHIPTOC supports only definite time characteristic.
For a detailed description of timers, see the General function block
features section in this manual.
Table 205: Reset time characteristics supported by different stages
Reset curve type
(F)PHLPTOC PHHPTOC Note
(1) Immediate x x Available for all operate time curves
(2) Def time reset x x Available for all operate time curves
(3) Inverse reset x x Available only for ANSI and user
programmable curves
The Type of reset curve setting does not apply to PHIPTOC or when
the DT operation is selected. The reset is purely defined by the Reset
delay time setting.
4.1.1.7 Application
(F)PHxPTOC is used in several applications in the power system. The applications
include but are not limited to:
• Selective overcurrent and short-circuit protection of feeders in distribution and
subtransmission systems
• Backup overcurrent and short-circuit protection of power transformers and
generators
• Overcurrent and short-circuit protection of various devices connected to the
power system, for example shunt capacitor banks, shunt reactors and motors
• General backup protection
