Circuits October 29, Lab The connection of the supply voltage must be fused externally with max 4A. Functions The reactive power and active power portions of the power source are continuously calculated in the control relay from the measured voltage and the signals of the current transformer. The display then shows “”.

The size of the capacitor stages has no influence on this setting. Automatic Power Factor Panel in Chennai.

All information on FRAKO

Before a reactive power control system can be put into operation, the target power factor has to be programmed.

In this way it can also be determined which switching outputs are in use. The installation and connection of the RM is only finished, once it has been installed and wired according to fraio instructions.

Commissioning After the control relay has been installed as described in section 3, the relay can be put into operation. The contact closes when either there is no mains voltage applied to the control relay or when an alarm is signalled. Control circuit is not connected properly or there is no control voltage There is farko neutral on the contactors.

Current transformer circuit interrupted or there is no current flowing on the secondary side. A different current measuring meter e. If the identification process is not concluded within 15 minutes there is probably a fault.

The reactive power control relay RM is a microprocessor-based control relay for intelligent control of capacitor banks with 6 control contacts. If the power factor shown does not coincide with the real power factor, the identification process must be repeated. During the identification process all the control contacts of the relay are individually switched on and off again.

Plug-in connector blocks supplied with the control relay Zero Current Trip: Fraako and reactive currents are measured seprarately. Get Best Price Request a quote. After voltage is restored the control relay switches the required stages on. If the 6th stage was already switched on “6.

The effects are illustrated by the two examples in Figure 6 and Figure 7. The order and the maximum value of the harmonics which have been exceeded, beginning with the maximum deviation, are displayed by multiple pressing of the “Set” button.

If the current transformer ratio is not set the value displayed must be multiplied by the CT ratio.

RM Power Factor Controller

See section 8, page 35 4. OFF” will appear on the display until the control relay has switched off the 6th stage after approx. The minimum apparent current for a correct power factor cos phi display is approx. Automatic Power Factor Panel. After this period the values can only be read read-only mode.

To the right of the four and a half character digital display there are three LEDs indicating which display mode is active, either “cos phi”, “Ampere”, or “Harmonic”. During installation and service work the control relay must be kept free of voltage. This is the recommended setting when using asynchronic generators in parallel.

This means that even when active frakko is fed back into the mains, the control relay ensures compensation for the reactive power which has been drawn from the mains. For such applications this feature can be disabled. The mode of operation of this adjustment can be seen in Figure 4 and Figure fraako.

Fixed stages are stages which are not included in the normal control cycle but are switched on immediately after the control relay is switched on and always remain switched on.
