Epcos br 6000 manual

Otherwise, menu point 11 is omitted. The specified discharge time is then also included in the normal display. Phase correction between voltage and current in the measuring system.

See example p. However, the measuring voltage may not exceed V if necessary, a voltage converter must be used. If the result varies from the nominal value, an error message is generated. This test can be stopped here. STEP [ For all standard settings three-phase , the measurement is converted and all outputs displayed as three-phase values symmetry in grid assumed. In the single-phase setting, display and control apply only to the singlephase value measured application: single-phase correction in asymmetrical grids.

The additional 2nd expert mode includes all messages for operation, warning and error which are displayed by the BR Here they may be deactivated separately. When deactivated, the indication of the message in the display as well as possible activation of the relay or effects on the control behavior are suppressed detailed list of all messages s. Also, the alarm relay may be programmed here as 7.

Activation of particular operation, warning and error messages s. The control response of the BR can be selected in programming mode. In principle, the controller has four different control modes: 1. Sequential connection In sequential connection, the required capacitor stages are successively connected and disconnected in stages last in - first out.

The ranking of each step always corresponds to the power of the smallest stage. Advantage: Exact definition of the next capacitor to be connected in each case Disadvantage: Long settling time, high switching frequency of the small stages In order to shorten the settling time, the BR switches several stages simultaneously for a large power-factor requirement.

This applies to all control types. The maximum dimensions of the simultaneously switching branches can be changed in expert mode. If the value of the smallest stage is pre-selected, the conventional sequential connection is obtained.

Loop connection In this variant, the controller operates in loop mode first in - first out which minimizes the wear on the capacitor bank, i.

Advantage: Balanced utilization of equivalent stages and thus an increased operating life of the capacitor bank. Disadvantage: This mode can only be used in control series with groups of the same stage power and long settling time, as every switching step corresponds to the value of the smallest stage. Intelligent loop connection default setting The intelligent control principle combines the advantages of the network-sparing loop connection first in - first out with a much faster settling time, even for large load skips, and reaches this goal with the fewest possible switching operations of the capacitor stages.

The optimized time response is achieved by the simultaneous switching of several or larger capacitor groups as a function of the missing power factor in the power line. Both the number of real switching frequencies of the capacitors as well as the turn-on times of the branches are considered.

Advantage: Reaches the target cos phi in a fast-optimized settling time with a low switching frequency of the capacitors. Combined de-tuning special case for combined de-tuned banks Within a combined de-tuned application, 2 adjoining equal steps are switched with just one joint choke.

This pairwise de-tuning requires an appropriate closed control series i. The controller complies with the requirements of the control regime while largely conforming to the intelligent switching behavior. An individual configuration of the ASCII-protocol is possible in expert-mode 1: points 26 and following. The controller must have been installed before being set up and operated. All network-specific parameters are fully programmed as described in Section 5 Programming by being entered in sequence and stored.

The controller is then set to automatic operation with the operating mode key. It is now ready for operation. Section 12 Maintenance and warranty The BR should need no maintenance if the operating conditions are observed. However, it is recommended that a functional check of the controller be performed in conjunction with the regular checking of the capacitor bank. In the event of any interventions in the controller during the warranty period, all warranty claims lapse.

Check phase position See above Current in measuring range? Line interruption? Wrong current-converter factor? Current transformer short-circuited? Check current-converter ratio Go through measuring current range Check connection and phase position!

All stages connected - target cos phi not reached: compensation network sufficiently dimensioned? Check connection and phase position! Capacitive grid, although all stages disconnected No measurement voltage! Alarm relay: after 10 min. The arrows indicate the control direction and not the line conditions. In strongly asymmetrically loaded lines, Line measurements allow the most favorable differences may occur between control phase for measuring the power factor to be r e s p o n s e a n d p o w e r - f a c t o r determined.

The current converter is set measurement, as the power factor is accordingly for the measuring current. No operating voltage Note: No display, alarm relay is activated open. Selectable from 1 sec It may be reached via the "Operating Mode key. In the control series editor, the various steps may be programmed up to a rating of 30!

The customer will decide whether the generated control series is of sense. Power Factor Controller BR Annex 2: Default settings Note: The following values for the default settings apply only if the controller is supplied directly from the works. Otherwise, these values are replaced by the basic settings made by the manufacturer of the compensation network optimal values for the relevant network. Parameter Default setting Programmed values of this system to be entered by manufacturer or operator.

Cannot be changed Cannot be changed. For example, coupling is useful when two separate installations are operating on two transformer supplies and a coupling exists for both systems. When the coupling is closed because only one supply is working , it is still possible to access the total compensation power of both installations via the coupling of the controllers.

The network is then operating in master-slave mode. When all stages of the first controller are connected, the second controller is taking over and switches the remaining stages. It is therefore also possible to extend networks easily. When coupling is requested, it is necessary to program "controller1 as master and "controller2 as slave in this menu point.

When the coupling switch is open, both installations are operating independently. When the coupling is closed, master-slave operation is initiated automatically. It is an advantage of this simple solution that an additional serial interface is not required.

NOTE: By coupling a BR with a dynamic controller BRT , a mixed dynamic system can be designed that implements economically the advantages of a dynamic fast network. This measuring device is able to determine the sum current of the complete PFC system as well as the current of single capacitor branches. By monitoring the current of the installed capacitors, extraordinary grid conditions e. In such a case, the power factor controller switches off the relevant compensation stages as long as the extraordinary situation continues.

Monitoring of the capacitor current also means monitoring of the capacitor condition damages, aging and thus gives the opportunity to avoid consequential damages. For this a current transformer has to be installed at the power input of the compensation system. During each switching operation, the actual current change is measured and compared to the rated current of the switched capacitor s. In between the switching operations the current of the complete system is monitored.

The relay is deactivated and the BR display shows E error for this step. The alarm relay is activated. A reactivation of the step is possible in manual mode. The BR display shows an inverted capacitor symbol. The current is further on checked periodically is the rated current reached again, the step is reactivated. Periodical measurements are performed to check whether the current reaches the nominal value again.

If so, the step is reactivated. Bus-connections in and out have always to be made directly to the relevant device! Reactive power Diff. Harmonics - voltage THD - voltage 3. I - converter sek.
