Generator protection schemes are designed to prevent damage to the generator and ensure safe operation.

• Differential protection: compares currents at both ends of the generator winding to detect internal faults

• Overcurrent protection: trips the generator if current exceeds a certain threshold

• Loss of excitation protection: detects loss of excitation voltage and trips the generator to prevent damage

• Reverse power protection: trips the generator if power flows from the generator to...read more

Electrical demand in kVA measures the power required by electrical equipment, factoring in both active and reactive power.

• kVA stands for kilovolt-amperes, a unit of apparent power in an electrical system.

• It combines both active power (kW) and reactive power (kVAR) to represent total power demand.

• For example, a motor rated at 10 kW with a power factor of 0.8 would have a demand of 12.5 kVA.

• Understanding kVA is crucial for sizing transformers and generators to meet load require...read more

SCADA stands for Supervisory Control and Data Acquisition system, used to monitor and control industrial processes.

• SCADA systems are used in various industries such as power plants, water treatment facilities, and manufacturing plants.

• They consist of remote terminal units (RTUs) or programmable logic controllers (PLCs) that communicate with a central computer system.

• SCADA systems provide real-time data, alarms, and control capabilities to operators for efficient monitoring an...read more
