In order to keep the wear on mr contacts to a minimum, the switching delay time should be set to less than 45 seconds only in exceptional cases. In order to permit the widest possible use of the control relay, multiple settings are available. If, however, the control relay failed to determine the connection mode after 15 minutes due to high load changes or phase imbalances, it is possible to enter the connection mode manually as per 96006 2.
Year of Establishment Otherwise the current portion is displayed and has to be multiplied by the CT ratio to obtain the actual value. Then the display will change to the last displayed value.
For a current loss of longer than 3 secs capacitor stages connected are switched off. There is either no voltage or the wrong voltage has been applied to the control relay. Four-quadrant power control with LED display when active power is generated into mains.
Faults 1 2 3 4 5 6 7 Possible Causes Necessary Action Control relay does not function, digital display remains blank.
The correct setting for a V voltage system and a current transformer with 5A secondary current can be taken from Table 3. Setting the limitation value of 1 and a target power factor feako 1.
RM Power Factor Controller
Check control circuit according to the circuit diagram; check fuses. The LED “Ampere” lights up. In order to keep the load on the current transformer as low as possible the supply lines should have a cross-section area of 2. If the limiting value is exceeded, there is an alarm signal, i. View Contact Call Seller Now. 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.

When the optional switching combinations are sorted gm to their capacity, the capacity difference between two successive combinations may only be 1. Continuous monitoring for defective capacitor stages through self adjustment of control program Zero voltage and zero current tripping with alarm signal. All other stages follow according to their capacity.
The display then shows “”. Page Page Summary of Instructions The following Figure 10 shows the characteristics of the control band when set for rj capacitive target power factor. Check the fuses and contacts of the capacitor contactors and perhaps current absorbtion. As already described the control relay tries to reach its programmed control band.
Fault in capacitor circuit. If the result is higher than 11, 12 must be subtracted. Apfc Panels in Chennai. If there is an interruption in the measurement voltage path, the control relay switches off all stages after about 1 sec.

If the RM does not act as described above, remove voltage source and check installation. The contact closes when either there is no mains voltage applied to the control relay or when an alarm is signalled.
The target power ftako setting is ignored. If this, however, is not possible due to lack of capacitor stages available, an alarm is signalised after several minutes depending on the size of the difference. If the reactive power portion exceeds certain threshold values, which the control relay has measured at the time of auto-adaption or are set as per section 5, a switching action will take place at the switching outputs.
