The displayed value is multiplied by 0. Check if capacitors are energized frsko switching. Foil keyboard with 4 buttons Design: Switching load up to VA max.
The capacitor stages are too wide. Otherwise the current portion is displayed and has to be multiplied by the CT ratio to obtain the actual value. If the CT ratio is programmed into the relay, the actual active current is displayed; otherwise the current portion is displayed and must be multiplied by the CT ratio to obtain the actual value.
It will shift to the inductive direction if the plus sign is used and to the capacitive direction if the minus sign is used.
RM Power Factor Controller
The RM checks stored stage currents at specific time intervals during normal operation. In order to permit the widest possible use of the control relay, multiple settings are available. Year of Establishment It is assumed that the connected capacitorstages are sufficiently dimensioned. In 21 For example: The “kink” in the fralo characteristic line is not reflected in the feedback operation but is extended at the point of intersection mr the reactive power centre line axis with the feed-back operation line.
These values determine the stage sequence.

If a stage was frqko as a zero stage without power the corresponding numbers would indicate this by flashing. When setting “OFF” the alarm is suppressed. The relay’s cyclic operations prolong the life of all connected devices by averaging the length of time the capacitor stages are switched on. 6906 Description The reactive power control relay RM is a microprocessor-based control relay for intelligent control of capacitor banks with 6 control contacts. ON” appears on the display wait until the control relay has switched on the first stage.
By pressing the “Set” button the display shows the maximum value of the factor by which the RMS current has exceeded the nominal current. Automatic Power Factor Panel in Chennai.
All information on FRAKO
The terminals for V and V are internally bridged. All other stages follow according to their capacity. Documents Flashcards Grammar checker. Stage display LED lights up but capacitor contactors are not activated End of delay time of approx. The connection of the supply voltage must be fused externally with max 4A. Current transformer is in the wrong place. On and off have the following meanings: A different current measuring meter e.
If the power factor shown does not coincide with the real power factor, the identification process must be repeated. Check the current transformer. In the case of inductive reactive current inductive reactive power one or more control contacts of the reactive power control relay r closed after the preprogrammed time delay.
The connection recognised by the control relay can be read under mode number in accordance with Table 2. 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 Check whether the correct operating voltage is applied to the control relay.
The Reactive Power Control RM automatically determines the location of the current and voltage sources automatic phase rotation.
