Suitable for current transformers with rated secondary current of 1A or 5. If this menu item is set to On, then every alarm displayed by the alarm LED will also cause contact 6 or 12 to close. When automatic response current identification is switched offthe relative value of the switch outputs must be programmed manually. For troubleshooting see section 6.
If rfako to Off the response current setup code and the value of the switch outputs must be programmed manually. This means that there are deviations from the types of connection shown that do not restrict the control process. Their innovative control characteristics meet all the requirements of modern industrial networks and make these control relays suitable for all applications.
Reactive Power Control Relay RM 2106/12
In contrast, the capacitor discharge time is fixed at one minute. Rear view j Connection for the current transformer m Connectors for the control contacts that switch the contactors.
Suitable for current transformers with rated secondary current of 1A or 5. However, the problem has been recognised 216 a simple confusion in the phase conductors or in the connection of the current transformer. The control relay delay time is adapted to the size of the deviation. The defect stages can be read out as the cause of the alarm.

Check for the contactors to be energized. The rrako selection is made in setup mode under Continuous monitoring for defective capacitor stages through self adjustment of control program Zero voltage and zero current tripping with alarm signal.
All activated capacitor stages are deactivated. Independent setting of capacitor switching time to match discharge time of capacitor stages.
Response current set too low. These values can be read under points and Working in conjunction with rfako power factor correction system, the device controls the programmed target power factor by activating or deactivating capacitors.
The maximum overcurrent factor Ieff. Alarms and troubleshooting Possible causes: The connection must be checked if deviations are extreme. A wide range of setting options are provided to enable the reactive power control relay to be used in the widest possible way. After a waiting fraok of about 10 seconds the switching status of the selected switch output is inverted.
Relays Frako – Control Relays Manufacturer from Chennai
The control relay 21006 to be connected to at least one capacitor stage to switch in order to determine the type of connection. Fault in capacitor stages. We have four different types of Power Factor relays, click on the tabs below to find more about the features of them.
FRAKO power factor control relays help in solving complex problems ranging far beyond the pure control of reactive power to a set target cos phi. Messages A1 and A2 can be acknowledged by pressing any key or are automatically acknowledged after a waiting period of about 30 seconds.
To assure correct operation of the reactive VA control system the following conditions must be taken into account when choosing stage ratings: Set the response current r, according to Table 1 or Formula 1. Deviations are not signalled and are not corrected automatically. Suitable for current transformers with rated secondary current of 1A or 5A.
For other mains currents or current transformers with unlisted primary or secondary current, the response current can be calculated according to the following formula: If, on the other hand, the work point is outside of the control band, the control relay will attempt to reach the control band with the 2160 possible number of switchings by means of specific activation and deactivation procedures. If automaticresponse current identification is 23 Note:
