Real Ispat & Power General Manager Interview Questions and Answers

Percentage impedance is a measure of a transformer's ability to limit short-circuit currents and is related to its performance.

• Percentage impedance is the ratio of the transformer's impedance to its rated voltage.

• It is a measure of the transformer's ability to limit short-circuit currents and protect the system.

• A higher percentage impedance indicates a higher impedance and better protection against short-circuit curren...read more

Short circuit is an abnormal connection between two nodes of an electric circuit that results in excessive current flow.

• Short circuit occurs when a low-resistance path is created between two points in an electrical circuit.

• Short circuit current is calculated using Ohm's Law: I = V/R, where I is the current, V is the voltage, and R is the resistance.

• Short circuit current can also be calculated by dividing the voltage by...read more

T&D losses refer to Transmission and Distribution losses, while AT&C losses refer to Aggregate Technical and Commercial losses.

• T&D losses are the losses that occur when electricity is transmitted and distributed from power plants to consumers.

• AT&C losses include technical losses (due to inefficient equipment and infrastructure) and commercial losses (due to theft and billing inefficiencies).

• Reducing T&D and AT&C losses...read more

Standard Performance indices are metrics used to measure and evaluate the performance of an individual, team, or organization.

• Standard Performance indices are quantitative measures used to assess the efficiency, effectiveness, and quality of performance.

• They provide a benchmark for comparison and help in identifying areas for improvement.

• Examples include Key Performance Indicators (KPIs), Balanced Scorecard metrics, an...read more
