A good and healthy battery generally has a voltage of 12.6V to 12.8V when fully charged. When it is put through the load test equal to CCA, the voltage drops from 9.6V to 10.5V, depending on the ambient temperature. Once the load is removed, the voltage shoots back to nearly 12.6V. What Are The Symptoms of Voltage Drop?
Some part of electricity is lost between the point of use and the power meter, known as voltage drop. The NEC recommends the maximum voltage drop to be 5% across branch circuits and feeders and around 3% across the branch circuits. Understanding how to calculate the voltage drop will help you ensure the system performs well and is safe to use.
I is the electric current determined in amperes (A) For example, if a current of around 10 amps flows through the circuit and the resistance in the circuit is 30 ohms, the voltage drop will be 10A × 30 Ω = 300 V. The concept of voltage drop describes the differences between the voltage supplied at the source and load.
Let's take an example to understand: If the single-phase 120V circuit carries around 10A current and the conductor impedance is 1.2 ohms per 1000 feet, the voltage drop in the 50 feet circuit length will be: Voltage Drop = (2 × 10A × 1.2Ω × 50 feet) ÷ 1000 = 1.2V. For a three-phase circuit, the voltage drop can be calculated as:
Another way to reduce the voltage drop is to decrease the wiring resistance. You can do this either by using a thick gauge wire or by reducing the length of the wire. Install Voltage Drop Compensator Installing the voltage drop compensator at the end of the cable with the highest voltage drop will help you monitor and adjust the voltage.
