  • Page 4 The secondary of an external current transformer must never be allowed to be open circuit when the primary is energized. An open circuit can cause high voltages, possibly resulting in equipment damage, fire and even serious or fatal injury. Ensure that the current transformer wiring is made through shorting switches and is secured using an external strain relief to reduce mechanical strain on the screw terminals, if necessary.

    (Data Display) and Chapter 7 (Viewing Status Information). 5.1 Capacitor Bank Control Options The C192PF8-RPR offers you three options to control capacitor banks in order to meet the conditions of your electrical equipment and avoid unnecessary switching. All options may be used at the same time when applied to different banks.

  • Page 50: Pfc Operation

    To specify the bank as a permanently switched bank, set the bank size parameter to On (see Section 4.13, PFC Setup). The permanently switched banks are switched in automatically when the PFC is put into either manual or automatic operation mode and before a switching program begins, and are switched out when the PFC shuts down, following all switching and re-connection time delays.
  • Page 51 the target. When no leading (capacitive) target power factor is allowed, only combinations that provide lagging (inductive) power factor will be checked. The banks are connected and disconnected starting from the low-size banks, following all pre-set switching and re-connection delays. Alternation of switching operations is provided when needed to avoid excessive deviation from the target power factor.
  • Page 52 Shutting the PFC Down From the PFC setup menu, set the PFC operation mode to OFF. This will put the PFC into Shut Down mode. Shut Down mode provides step-by-step disconnection of all the capacitor banks that are under the PFC control. The banks switch out progressively, following disconnection intervals (switch-off delays).
  • Page 53 PFC will not take into account the status of the digital input. The second setpoint will not even appear in the PFC setup menu. If you want to use different target setpoints and switch them depending on the time schedule or another external condition, specify the operational setpoints as SP1-2.
  • Page 54 defined setpoint operate delay. This makes the trigger less sensitive to fast changes in load thus avoiding excess switching. The operate delay timer is reloaded each time the measured power factor oversteps the setpoint range limits. The allowable range for the operate delay is 1 to 3600 sec. The default value is 3 sec.
  • Page 55 Normally, the capacitors discharge through fixed resistors that are connected to the capacitors directly or via auxiliary contacts of the contactors. Refer to the capacitor data sheet for the recommended discharge time for your capacitors. The re-connection delay can be adjusted in the range of 3 to 3600 sec. The default setting is 300 sec.

    (with minimal cycling whenever possible). In the C192PF8-RPR, all protective functions are provided through the universal mechanism of programmable alarm setpoints (see Section 4.6, Alarm/Event Setpoints Menu).
  • Page 58 5.3.2 PFC Protection Setpoints Protection against Voltage Interruptions The fast disconnection of the capacitor banks is required in the event of short- term voltage interruptions that would cause damage to the still-charged capacitors when the voltage is restored. The No-Volt alarm override condition (see Table 4.6) along with the Hard Switch- Off action can de-energize the output relays in approximately 25 ms whenever voltage interruption is detected.
  • Page 59 Protection against High Harmonics High THD protection prevents damage to capacitors at high levels of voltage harmonics, which can be caused by voltage resonance at a higher frequency. The effect of the high THD setpoint protection is limited progressive disconnection of the capacitor banks until resonance conditions disappear, and then, after a long safety delay, returning the PFC into normal operation.
