Testing of Overcurrent Relay: Test benches are used for proving the design characteristics of relays. These are provided with accurate timing apparatus and calibrated current and voltage supplies. The basic…
Bus Zone Protection: Bus Zone Protection includes, besides the bus itself the apparatus such as circuit breakers, disconnecting switches, instrument transformers and bus sectionalizing reactors, etc. Although bus zone faults…
Carrier Pilot Protection and Microwave Pilot Protection: The problem of providing economically an auxiliary channel by means of pilots for long lines directed attention to carrier techniques. In this case…
Distance Protection by Reactance Relays: Like impedance relays, Distance Protection by Reactance Relays are also amplitude comparators and thus require an additional directional unit. Although the performance of reactance relays…
Distance Protection Impedance Relay: Distance Protection Impedance Relay - It has already been pointed out that the impedance is directly proportional to the length of the line, and hence an…
Intel 8096 CPU Structure: The major components of the CPU on the 8096BH are the register file and the register ALU (RALU). The Intel 8096 CPU Structure consists of a…
8051 Interrupts: The 8051 Interrupts provides 5 interrupt sources. The 8052 provides 6. These are shown in Fig. 12.28. The external Interrupts INT0 and INT1 can each- be either level-activated…
Intel 8051 Architecture and 8031 Architecture: Fig. 12.2 shows the Intel 8051 Architecture and 8031 Architecture. It consists of a Central Processing Unit, two kinds of memory (data RAM plus…
