    Grenada Outdoor High and Low Voltage Complete Set of Equipment

    This prefabricated substation is a complete set of substation products reasonably combined with a booster transformer, high-voltage switchgear, low-voltage switchgear, power transformer, and other auxiliary equipment with the box body. The GGJ-type low-voltage distribution reactive power compensation integrated cabinet is a new-generation outdoor distribution cabinet designed based on the principles of safety, economy, rationality, and reliability. The role of the box transformer for wind power is to step up the 0. 69KV electric energy generated by the wind turbine to 35kV, and then transmit it to the wind farm. KYN28 Metal clad central removable switchgear cabinet (hereinafter referred to as switchgear)is a three-phase AC 50Hz indoor distribution device,which is used to receive and distribute 3-12kV network.

    Relay protection timing point

    Protection relay setting is the process of choosing the current threshold and time delay at which a relay trips a circuit breaker during a fault. The goal is to isolate only the faulted section — quickly enough to protect equipment, but with enough delay to let downstream relays act. How protective relay testing works: secondary and primary injection, pickup and timing checks, curve verification, and the relay's role in a coordinated scheme. The principle is to grade the operating times of the relays in such a way that. Overcurrent relays are the most common form of protection used to operate only under fault conditions. There are two main types of time relays. Electromechanical relays have moving parts. Ensure that the minimium, un-faulted load is interrupted when the protective.
