• I create a detailed project plan outlining tasks, timelines, and resources.

• I regularly monitor progress, identify risks, and implement mitigation strategies.

• I communicate effectively with stakeholders to ensure alignment and address any issues prom...read more

CT stands for Current Transformer and PT stands for Potential Transformer.

• CT is used to measure high currents by stepping down the current to a manageable level.

• PT is used to measure high voltages by stepping down the voltage to a safe level.

• CTs and PTs are commonly used in electrical power systems for protection, metering, and control purposes.

• CTs and PTs are typically connected to instruments such as relays, meters, ...read more

3 core PT & 1 core PT are types of power transformers used in electrical systems.

• 3 core PT has three separate cores for voltage measurement while 1 core PT has only one core.

• 3 core PT is more accurate and reliable than 1 core PT.

• 3 core PT is used in high voltage applications while 1 core PT is used in low voltage applications.

• Both types of PT are used to step down high voltage to a lower voltage for measurement or prot

Ohm's law is a fundamental law in electrical engineering that relates the current flowing through a conductor to the voltage applied across it. Power system refers to the network of electrical components and devices that generate, transmit, and distribute electrical power.

• Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

• Power system i...read more

A substation is an electrical system that converts high voltage to low voltage or vice versa. ACSR conductors are used in power transmission.

• Substations are used to control and distribute electrical power

• They can be classified as step-up or step-down substations

• ACSR conductors are made up of aluminum wires wrapped around a steel core

• Types of ACSR conductors include Lynx, Panther, Zebra, etc.
