Frequency range The RE. 216 protection system can be set to operate at a power system frequency fN of either 50 Hz or 60 Hz. The algorithms representing the protection functions have been optimised to produce the best results at the rated frequency fN. Deviation from the rated frequency cause an additional error. The O/P of the frequency function can be used to block other protection functions in the event of excessive frequency variation.

System parameter settings 3.4.1. Entering the relay configuration The relay configuration only has to be entered when making settings 'off-line' or when the hardware or software of the RE. 216 scheme has to be changed. The configuration does not have to be entered when making settings 'on-line'. The corresponding parameters are to be found in the sub-menu "Relay configuration" of the "Change hardware functions" menu. The units fitted in a rack, the rated frequency, the software key and the type designation for a particular application are entered under "Relay configuration". 3.4.2. Entering the parameters for the c.t./v.t channels The following two sub-menus are used in conjunction with the c.t./v.t. inputs: C.t./v.t. channel type The type of c.t./v.t. channel is determined by the input transformers installed. The entry of the type specifies:
c.t. or v.t.
single or three-phase
metering or protection core
Y or delta connection.

C.t./v.t. channel 

reference value A separate reference value can be entered for every c.t./v.t. channel. They enable the rated voltages and currents and also small differences of the primary system c.t's and v.t's to be compensated. Note that three-phase voltages (or currents) assume the value of the R phase channel. If, for example, the rated voltage of the primary system v.t. is neither 100 V nor 200 V, reference values have to be entered for the corresponding channels. Assuming a rated voltage of 110 V, the reference value to be entered becomes: Reference value for voltage channel

110 100 1100 V V . Comment for an c.t./v.t. channel Facility is provided for the user to enter a comment for each analogue channel, which is displayed together with the channel type when the corresponding c.t./v.t. input parameter of a protection function is selected. 3.4.3. Entering latching parameters Every tripping and signalling channel can be set to a latching or non-latching mode via the sub-menu "Change tripping or signalling channel".
