For a target power factor other than 1. It has to be passed by both capacitor and consumer current. Find more suppliers in Chennai Power Controllers in Chennai. By pressing the “-” button once “6. The terminals for V and V are internally bridged. Setting the limitation 960 of 1 and a target power factor of 1. The current transformer can be installed in any phase. In order to reach the set mode again after this period, it is necessary to disconnect the control relay from its source for a short period of time.

If this ratio is exceeded by the factor 906 for at least one minute due to harmonics and the resulting resonance phenomenon, the control relay switches off all stages which have been switched on. Specific rules and regulations must be observed. Call Send a quick message. The minimum apparent current for a correct power factor cos phi display is approx. 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.

Before a reactive power control system can be put into operation, the target power factor has to be programmed. Suitable for current transformers with rated secondary current of 1A or 5A. After acknowledgement the flashing alarm marker goes out.

Pressing the “Set” button again shows the actual power factor on the display and the alarm marker “Power Factor” no longer flashes. The display shows the active current on the fundamental oscillation in the current transformer CT circuit.

While waiting the switching counter of this stage will be displayed for a short moment. Relay was not in fraki mode. That means for example: See fra,o 8, page 35 4.

Control circuit is not connected properly or there is no control voltage There is no neutral on the contactors. The connection must be manually programmed as per Table 2. In the case of other voltages or current transformers for which the primary or secondary current is not given, the response current can be calculated from the general equation: How to put out the alarm is explained in section 5.

An effective supervision of the reactive power control system capacitor bank is secured frxko the power factor display. The response current corresponds to half the width of the tolerance band, within which the reactive current can change without capacitor stages being switched on or off.

It must not be possible to touch the applied voltage at the alarm contact. Otherwise the current portion is displayed and has to be multiplied by the CT ratio to obtain the actual value. By pressing the “Set” button again the display shows the actual power factor and the alarm marker “Ampere” no longer flashes.

Fault in capacitor circuit. Faults 1 2 3 4 5 6 7 Possible Causes Necessary Action Control relay does not function, digital display remains blank. The maximum load for the alarm contact is VAC and frajo Amps. The power factor cos phi display value is the result of a mathematical calculation, which ensures accuracy over the entire range down to values close to 0. Check the current transformer. To prevent unintentional reprogramming, the set mode can only be activated within the first 5 minutes after the operating voltage has been applied.

For a current loss of longer than 3 secs capacitor stages connected are switched off. OFF” will appear on the display until the control relay has switched off the 6th stage after approx. It is assumed that the automatic connection and stage current identification are switched on see section 5.

Current transformer circuit interrupted or there is no current flowing on the secondary side. Refer to section 2. Additionally all safety and commissioning instructions of the Reactive Power Control System are to be observed. In case of low voltage networks being fed by frao transformers switched in parallel, the capacitor current is distributed to all the transformers. This causes the RM to switch capacitor stages onto the power source supply, as and when required, in order to achieve the programmed target power factor.

Installation and Connection The control relay should preferably be connected to the three-phase system as shown in page This number corresponds to the first variable which is displayed or can be changed in the following sequence see Table 1. If the first stage was already switched on “1. Automatic Power Factor Panel in Chennai.

All failed stages are switched on from time to time in order to re-check their capacitance. If measurements are not carried out via a summation transformer, the current change, measured by the control relay, is too low when switching on the capacitor stages, which can lead to errors during the automatic stage identification process.

This process can take up to 15 minutes. The relay’s cyclic operations prolong the life of all connected devices by averaging the length of time the capacitor stages are switched on. If the set mode has been activated within these 5 minutes, it remains available for one hour. However, we recommend that if capacitor stages are added at a later date, the set-up frakoo be repeated see section 2.
