Protection Relays & Systems are the backbone of power system engineering; their function is to provide a means to monitor and protect electrical equipment. The power engineer must consider the protection technology, response timing, selectivity, adjustable settings, load flow and fault conditions. The K2CM-2H is a series of protection relays developed by Tehal Electronics to meet the requirements of high-efficiency and reliable protection for medium-voltage systems.

The K2CM-2H protection relays are versatile and reliable for all type of industrial and utility protection solutions. These relays are designed to offer high speed protection for a range of fault conditions such as short-circuit, overload, out of phase, ground fault and unbalanced current and voltage. With the help of the multi-functional digital panel, users can easily set all the parameters required for successful operation. In addition, the device offers advanced features such as LED indicators, multi-level scanning, remote monitoring and reset buttons.

The main application field of the K2CM-2H relays is in protection and control of various medium-voltage systems such as busbars, power transformers, ring main units and transformer banks. The device is also suitable for protection and control of sub-stations and distribution systems. One of the most important function of the K2CM-2H protection relays is its ability to detect faults that occur on the power system, and then provide protection against it.

The K2CM-2H also has an adjustable protection function which allows users to adjust its sensing levels and response time. This makes it ideal for applications such as overload protection and short circuit protection. Furthermore, users can also use the device to monitor power system performance and detect any abnormalities. The device’s ability to accurately detect and react to abnormal conditions helps to reduce the chances of system failure due to faults.;

The working principle of the K2CM-2H protection relays is based on the use of electronic components and logic circuits to measure, monitor and protect the system from faults. The protection relays are programmed using logic circuits to detect when a fault has occurred on the power system. The logic circuits are then used to adjust the response time and trip the protection relay when the defined parameters are met. The K2CM-2H protection relay operates on the principle of time-lag protection and is designed to allow a predetermined time delay before tripping. This provides the system with a grace period during which the fault can be identified and isolated.

In conclusion, the K2CM-2H protection relays remain one of the most reliable and versatile protection solutions for medium-voltage systems. They offer high speed protection for a wide range of fault conditions, adjustable protection levels and response time, remote monitoring, and LED alerts. With its advanced features and adjustable settings, the K2CM-2H offers an efficient and reliable protection solution.
