Protection relays and systems are important pieces of equipment in electrical power systems to protect substations and transmission lines. They detect faults and isolate the affected sections of the power system quickly. In modern power systems, microprocessor-based protection relays are commonly used. One of the most popular types is the K2CM-1M Protection relay.

The K2CM-1M protection relay is a microprocessor-based relay developed for the purpose of providing protection and control for medium voltage network. It is designed to provide both overcurrent and directional functions, and offers selectivity, secure operation, and flexibility in the network protection.

The K2CM-1M is mainly used in power system networks to protect short-circuits, phase-to-phase faults, phase-to-ground faults, and ground faults. It is installed in medium voltage network to sense and detect currents on the power system, and isolate the affected parts of the power system in case of a fault. The K2CM-1M has the ability to detect faults in both power and data signals.

The K2CM-1M\'s working principle is based on the comparison between the measured current and the set values. The protection relay compares the measured current with its set value. If the amplitude of the measured current is higher than the set value, the relay will operate and trip the circuit. The set value can be adjusted depending on the application of the relay. The relay can be used for various applications such as protection for transformers, generators, motors, and transmission lines.

In addition to protection, the K2CM-1M can also be used for load shedding. It is able to detect overloads due to a gradual rise in current and operator malfunctions. In such cases, the relay will immediately trip the load and prevent a circuit overload. This can help reduce downtime and conserve energy in the process.

The K2CM-1M is also capable of detecting hazardous overvoltage on the power system. This can occur due to a sudden remote start or a fault in the system. In such cases, the relay will trip the circuit to protect it from the overload.

Another feature of the K2CM-1M is its ability to detect ground or earth faults. Ground faults can be due to improper connections or poor insulation. The relay will detect the fault and isolate it in order to protect the power system from any damage.

The K2CM-1M is widely used in protection relays and systems throughout the world. It is designed to provide maximum protection by offering selectivity, secure operation, and flexibility. In addition, the K2CM-1M can be used for load shedding, fault detection, and protection from hazardous overvoltage. It is a reliable and efficient protection device which is essential for ensuring the safety of power systems.
