A New Generation of Intelligent Electronic Devices Market

Most of the nations worldwide are trying to raise their electricity production in order to complement the increasing industrialization and urbanization. This factor has significantly contributed to the rise of substation installation in order to deliver electricity to various remote parts of a nation. A substation is used to step up current and voltage or vice versa for transmitting electricity to long distances.

Thus, a substation typically consists of equipment such as circuit breaker, transformer, capacitors and voltage regulators which perform transmission, distribution and protection of equipment’s from both the ends. This makes substation an important part of power system which needs constant monitoring and maintenance for smooth operation. Intelligent electronic device helps to monitor, control and protect the substation equipment’s from unpredicted faults resulting in disruption of power supply.

Intelligent electronic devices consist of a group of microprocessor controlled components such as switching, control and communication units. Switching units comprises devices such as protective relay, electrically operated on-load tap controller and electrical isolator which operate in substation to mechanically isolate the system in case of possible fault. Some switching units also continuously monitor and collect data which is fed to control units through communication devices. Communication devices comprises Ethernet cables, wireless transmission and power line communication carrier (PLCC). Today, most of the intelligent electronic devices manufacturers provide communication through Ethernet cables and wireless communication.

Control units consists of a system which helps to monitor and control the remote terminal unit (RTU) or switching units in real-time. Further, it also collects historical data from switching units thereby providing detailed analysis to the operator. Intelligent electronic devices also consist of monitoring systems, supervisory control and data acquisition (SCADA), human machine interface (HMI) and digital meters which help to provide additional information of overall health of substation systems.
