In order to ensure that after switching-off, a capacitor stage is not switched on again before the capacitor has been sufficiently discharged, the switch-off time can be adjusted to the specific needs discharge mode. For exampleif “1. The stage currents ascertained are then stored. When choosing mode the display shows “0”. All failed stages are switched on from time to time in order to re-check their capacitance.
The installation and connection of the RM is only finished, once it has been installed and wired according to these instructions. Automatic Power Factor Panel. Get best deals for coconut.
Use ammeter to check current on secondary side of CT. Switched off -3 -2 cap Reactive current Switched on 1 -1 One scale division corresponds to 0. Before a reactive power control system can be put into operation, the target power factor has to be programmed. The discharge time can be set between 5 and seconds. How to put out the alarm is explained in section 5.

Check the control circuit according to the circuit diagram and check fuses. Additionally all safety and commissioning instructions of the Reactive Power Control System are to be observed. When the optional switching combinations are sorted according to their capacity, the capacity difference between two successive combinations may only be 1.
The set discharge period is maintained. For a current loss of longer than 3 secs capacitor stages connected are switched off. To keep the function “Zero Framo Alarm” operational the supply voltage of the control relay should be connected in the same phase as the contactor voltage.

An effective supervision of the reactive power control system capacitor bank is secured by the power factor display. If the threshold values set for “switch-on” and “switch-off” are exceeded and no further change can take place in the output stages, the alarm signal functions except for the cos-phi alarm being switched-off; see mode All measuring instruments in current path must be connected in series Finer adjustment of the capacitor stages is required.
These values determine the stage sequence. Call Send a quick message. As already described the control relay tries to reach its programmed control band. The pre-mounted terminal connections allow a quick and easy installation.
Pressing the “Set” button again shows the actual power factor on the display and the alarm marker “Power Factor” no longer flashes. Functions The reactive power and active power portions of the power source are continuously calculated in the control relay from the measured voltage and the signals of the current transformer. Documents Flashcards Grammar checker. In order for the relay to be able to determine the mode of connection at least one capacitor stage must be operational.
The display shows “” and after a discharge time for the capacitors the stages are switched on and off again one after the other. There is either no voltage or the wrong voltage has been applied to the control relay. The control relay is electrically connected through a multiple connecting terminal supplied with the relay.
Product Description The reactive power control relay RM is a microprocessor-based control relay for intelligent control of capacitor banks with 6 control contacts.
The set target power factor is therefore the upper limit of the control band. The alarm markers remain active after the alarm until they are acknowledged by pressing the “Set” button.
Power Factor Correction Panel. The contact closes when either there is no mains voltage applied to the control relay or frakl an alarm is signalled.

View from below 3 P Contents 1. When voltage is initially applied to the control relay, it determines the location of the current and voltage sources automatic phase rotationi. Check whether the capacitor contactors have been activated.
