CCEX button in the main window.
| PARAMETER |
DESCRIPTION |
| Manager
Status |
Enables or disables all CCEX activities. When
Enabled, any enabled sub processes are allowed to execute. When Disabled
no automatic activities are allowed to execute. |
| Management Method |
Parameter value determines on what level CCEX
does capacitor control. Possible values are By Feeders, By
Substations, and Global. |
| Control Parameter |

the control parameter for doing capacitor control. Possible values are Reactive
Power, Power Factor, and NONE. In the latter case CCEX
is essentially turned off, but manual capacitor control is still
possible. |
| Connect Threshold |
Parameter specifies at which value of control
parameter CCEX must connect capacitor bank(s) to the power grid. |
| Disconnect Threshold |
Parameter specifies at which value of control
parameter CCEX must disconnect capacitor bank(s) from the power
grid. |
| RUEX Replication Period (Seconds) |
Parameter specifies how often CCEX checks on
RUEX for new data. When new data is available CCEX replicated the data
for its own use. |
| Demand Units of Measure |

Units of measure (VAr, kVAr, etc.) used for
recording and display purposes. |

Parameter specifies number of historical
control parameter readings to hold for global control parameter trending displays. |
| Alarms |

Enabled
visual and audio alarms are generated in addition to alarm log entries
when error conditions occur. When Disabled, log entries are generated
only. |
| Management Cycle Logs |

event log entry for each global management cycle, reporting
demand, reactive power, power factor, number of capacitors connected to
the power grid, etc. |
| Capacitor Operation Logs |

recorded in CCEX event log file. The following options are available:
All - Every control code is recorded; State Changes Only - Only control
codes which cause state change (OnàOff

however alarms persist. The only way to get rid of alarms is to archive
the file. |
