A given solar cell has the following specifications: Open-circuit voltage, Voc: 0.7 V Short-circuit current, Isc: 3.5 A Short-circuit current, Isc: 3.5 A Short-circuit current, Isc: 3.5 A If the solar cell operates at maximum power point, calculate the efficiency.
The magnitude of earth fault current for a given fault position within a winding demands upon the winding connections and method of neutral grounding. Earth fault protection for an electric motor is provide by instantaneous relay having a setting of approximately 30% of motor rated current in the residual circuits of two CTs and with ground wire.
