The residual current transformer is to be permanently installed when the distribution board is free from voltage. The DRCA 1-MC cable is to be used for measurement. The installation of the transformer must only be performed by qualified electricians. -

GENERAL SIGNAL ANALYSIS Frequency Analysis Note � �� � �� �� � �� � �� �� If, for example, a trigger level of 300 mA is set and enabled, a residual current of 200 mA would no longer be displayed. In order to avoid erroneous measurement, the trigger is therefore disabled by default. -

DATA STORAGE 6. Data Storage Triggermode The 'Trigger' module was developed to enable recording of switch-on and switch-off processes. Signals that only exist for a short time and In addition to the values shown in chapter 5.2 ('RMS value diagram'), have steep edges cannot be recognised in other programs, as they the peak value determined in each measurement cycle is also saved. -

DATA STORAGE As soon as the measurement is started, all elements are blocked to the user, except for 'Cancel Storage'. The measurement ends automatically once the 'Measurement end time' is reached, although it can be ended before this using 'Early termination'. Data recorded up to this point is saved. -

DCTR B DMRCD 1 B+ DRCM 1 B+ produced by Doepke Schaltgeräte GmbH are available, which can measure the residual current to be evaluated. As the program operation for each product group is identical, the function is explained using one selected group (DFS 4 B). -

Types with tripping currents of 100 mA can be seen in the tripping frequency response in Fig. 17. Further information on this topic can also be found in Doepke's brochure: 'AC-DC sensitive residual current devices: RCD Type B'. -

If several programs are open at the same time, interruptions may Double the sampling frequency is required for meaningful sampling occur during the measurement. of a signal that is continuous over time. The DRCA 1 uses a sampling rate of greater than 200 kHz. Therefore, the maximum frequency that Switch selection after RCD overview can be recorded is around 100 kHz. -

The USB cable, which is connected to the PC/notebook, is connected hazard point. All connections for measuring devices in category I are via a USB socket. The transformer is connected to the DRCA 1-CT labelled in this way. socket with the supplied DRCA 1-MC measuring cable. -
