As the most widely used product in the field of relay and protection, Transmission Line Protective Relay is commonly adopted in substations, distribution stations, hydropower stations, pumping stations and photovoltaic power plants. Core Functions & Types of Transmission Line Protection…

Generators run continuously under harsh conditions with high voltage, heavy current and high rotating speed, prone to faults such as stator winding short circuit, rotor grounding and loss of excitation. Severe faults will damage the generator and even cause power…

During operation, motors shall be protected or alarmed against overload, phase loss, locked rotor, short circuit, overvoltage, undervoltage, earth leakage, three-phase unbalance, overheating, bearing wear as well as stator and rotor eccentricity. Therefore, dedicated protection is essential for electric motors.…

What is a digital fault recorder Fault Recorder in Substation, also referred to as Digital Fault Recorders or Fault Recording Devices, is essential equipment for power system automation. Digital Fault Recorder can be used for dynamic recording and fault analysis…

Protection Relays for Transformer are protective relays used to detect electrical faults and abnormal operating conditions in power transformers. Depending on the transformer rating, winding configuration and protection requirements, a transformer relay may provide differential protection, overcurrent protection, earth-fault protection,…

In power system protection of relay, Differential Relay Protection represented by differential current protection is a familiar concept to those in the power industry. When a fault occurs within power equipment, differential protection can quickly and accurately isolate it, thereby…
