Control Board Details
The protection of electrical system is required to maintain any device in operation without failure. There are various types of protective devices used in Power Systems. The knowledge of protective devices helps to use them smartly and avoid system breakdown.
Electromechanical Relays Workbench is a useful learning product for electrical Power Laboratories. Over Current Relay monitors general balanced overloading and have current/time settings. These settings determine the protective schemes. The Earth Fault Relay detects the leakage current well before they cross threshold limit.
The Different Relay operates due to differential current flowing in the circuit. When current between two sections vary from a known and permissible value, the relay gets tripped and protects the connected device.
The relays have different tripping time characteristics with different current conditions. These are classified in accordance with their characteristic curves which indicate the speed of tripping operation. The typical settings for relay are 0.5-2 Amp. It is an ideal platform to enhance education, training, skills & development amongst our young minds.
