3.1.6 Fault Detector Module
Models 400 and 500 series have an independent fault detector in the form of a check relay, and
provide the highest order of security against non-power system fault tripping.
As shown in Figure 3.1.6.1, the fault detector module consists of an analog filter, multiplexer,
analog to digital (A/D) converter, main processing unit (MPU) and output auxiliary relays. The
entire processing from filtering to operation for the measuring elements and output control is
carried out within this module.
The fault detector module receives 3 voltage (Va, Vb, Vc) inputs and 4 current (Ia, Ib, Ic, 3I0)
inputs. The analog filter carries out low-pass filtering for the corresponding current and voltage
signals.
The A/D converter has a resolution of 12 bits and samples input signals at sampling frequencies of
2400 Hz (at 50 Hz) and 2880 Hz (at 60 Hz).
The MPU implements 60 MIPS and uses a RISC (Reduced Instruction Set Computer) type 32-bit
microprocessor. Once the fault detector measuring elements start operating, the high-speed
auxiliary relays FD1 and FD2 operate.
The fault detector module incorporates 8 binary output auxiliary relays (BO1-BO8) each with one
normally open contact.
