Technical Strategies to Improve Transmission Line Efficiency
In modern power systems, the efficiency of transmission lines directly affects overall grid performance, operating costs, and reliability. Since transmission losses primarily occur due to conductor resistance and reactive power flow, engineers must carefully evaluate both design and operational strategies to minimize these losses. Below is a detailed technical review of methods to improve transmission…
How do you select cable size for a motor or load
Selecting the right cable size is important for both safety and efficiency. An undersized cable may overheat, cause voltage drops, or even lead to fire hazards. An oversized cable increases cost unnecessarily. Cable size is selected based on the following key factors: Current Carrying Capacity (Ampacity): The cable must handle the full-load current of the…
Difference between MCB, MCCB, ACB, and VCB
MCB, MCCB, ACB, and VCB are most common types of Circuit breakers. Circuit breakers are essential devices that we use to protect electrical systems from faults and overloads. They come in different types depending on the application, voltage level, and breaking capacity. MCB (Miniature Circuit Breaker) MCCB (Moulded Case Circuit Breaker): ACB (Air Circuit Breaker):…
