• Low-voltage applications (such as high-current landscape lighting) with field connections that are exposed to …
Battery Protection
The essential parts of BMS are overvoltage and undervoltage protection mechanisms. The active monitoring of battery voltage is the first checkpoint. With the help of voltage sensors, the battery''s voltage is constantly monitored and the data is sent to the BMS, and after this, the correct actions are taken by BMS which is based on the readings.
The Top Culprits: What Causes Transformers to Overheat?
Transformers are an essential component of electrical systems, and they play a crucial role in stepping up or stepping down the voltage levels as required. However, sometimes transformers can overheat, leading to potential damage to the equipment and the system. In this article, we will discuss the causes of transformer overheating and how it can […]
How is it possible to have high voltage and low current? It seems …
I have read different forums and watched a few s (in addition to my textbook readings) and the explanations seem to fall short. The issue seems to be how we are first taught about a direct relationship between voltage and current (that is, an increase in voltage renders an increase in current if resistance remains the same) and then we''re …
Electric Motor Overheating: The Signs and Solutions
The wrong voltage supply: Too many volts or too few volts can be damaging to a motor. When your motor doesn''t have the right voltage support, it needs to work harder to perform, which causes parts to overheat. A poor surrounding environment: A motor needs room to breathe so it can perform at its best. If your machine is running in a hot ...

Alternator Failures: Low Voltage To The Battery
Voltage, current checks. The actual output voltage produced by the alternator will vary depending on temperature and load, and will usually be about 1.5 to 2 volts higher than battery voltage. At idle, most charging systems produce 13.8 to 15.3 volts with no lights or accessories on.
current
Many people have posted about this in the past, but check the voltage drop of the L293D, which can be as high as 3.6 V (1.8 V lost on the high side, 1.8 V lost on the low side). This means your motors are only seeing half the voltage of the battery (7.2 V - 3.6 V), and the remaining is wasted as heat in the L293.
ELECTRICAL SAFETY – Applied Industrial Electricity
Even if the circuit voltage was low, the normal current could be high enough that an injurious spark would result at the moment the last meter probe connection was established. Another potential hazard of using a multimeter in its current-measuring ("ammeter") mode is the failure to properly put it back into a voltage-measuring ...
