This is essential to ensure that the system does not oscillate. To keep the function “Zero Voltage Alarm” operational the supply voltage of the control relay should be connected in the same phase as the contactor voltage.

The stage which has th exceeded the limit e. The target power factor setting is ignored. Circuits October 29, Lab By pressing the “Set” button the peak value is displayed. 966 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 Fault in control vrako contactors do not switch Fuses of the capacitor stages are defective or missing.

Preset up to three fixed capacitor dm which will be excluded from normal automatic operation.

RM Power Factor Controller

In order to keep the wear on the contacts to a minimum, the switching delay time should be set to less than 45 seconds only in exceptional cases. During installation and service work the control relay must be kept free of voltage. Suitable for current transformers with rated secondary current of 1A or 5A. Active and reactive currents are measured seprarately. If the set mode has been activated frakl these 5 minutes, it remains available for one hour.

If this ratio is exceeded by the factor set for at least one minute due fraki harmonics and the resulting resonance phenomenon, the control relay switches off all stages which have been switched on. The display then shows “”. In this case the LED “Regeneration” lights up.

In case of a capacitive cos-phi outside the band range the alarm signal functions as well. This is the recommended setting when using asynchronic generators in parallel.

This process can take up to 15 minutes. The reactive power control relay RM is a microprocessor-based control relay for intelligent control of capacitor banks with 6 control contacts. When the apparent current falls below 0. Excellent after sales service and track record of consistent performance levels put BARON as a Leader in their line of activities. Should the control relay fail to identify the current and voltage source due to power instabilities, repeat the procedure when the power has stabilized.

By pressing the “Set” button again the display shows the actual power factor and the alarm marker “Ampere” no longer flashes.

If S1 k and S2 l are connected the wrong way around or the CT is installed in wrong direction, connection mode number must be added by 6. The following Figure 10 shows the characteristics of the control band when set for a capacitive target power factor. Failure in automatic Repeat identification process.

Baron Power Ltd has rrako Installations belonging to the prestigious quality conscious clients. The voltage applied to the voltage path of the control relay is too small. Check if the position of current transformer corresponds to the circuit diagram.

Technical Data At the same time, the alarm contact closes and the “Alarm” LED lights frrako for as long as there is no voltage applied to the measurement input terminals of the control relay. The switching sequence does not take into account the fixed stages.

From this mode of display the compensation effect of the capacitor stages e. If the first stage was already switched on “1.

The alarm markers remain active after the alarm until they are acknowledged by pressing the “Set” button. Find more suppliers in Chennai Power Controllers in Chennai. The discharge time can be set between 5 and seconds. However, if the control relay operates outside the band range, the RM will try to come within the band range with the minimum of switchings.

The LED fraoo indicates that generative active frrako is fed back into the mains. In case of low voltage networks being fed by several transformers switched in parallel, the capacitor current is distributed to all the transformers.

In the case of fixed stages being used, the smallest stage has to be connected following the last fixed stage. The control relay must be kept voltage free during wiring and installation works.
