Wire colour coding is a standard method of identifying the function of different wires in electrical systems.
In North America, the standard wire colour coding for AC power circuits is black for hot, white for neutral, and green or bare copper for ground.
In Europe, the standard wire colour coding for AC power circuits is brown for live, blue for neutral, and green/yellow for ground.
Different industries may have their ow...
Crimping is a process of joining two pieces of metal or other materials by deforming one or both of them to hold the other.
Crimping is commonly used in electrical work to join wires to connectors.
It is also used in plumbing to connect pipes together.
Crimping tools are often used to create a secure connection.
HV stands for High Voltage, which refers to electrical potential difference between two points that exceeds the safe threshold.
HV is typically considered to be any voltage above 1000 volts.
High Voltage is commonly used in power transmission and distribution systems.
HV can be dangerous and requires proper safety precautions when working with it.
HV and air leak tests are essential for ensuring safety and quality of products before delivery to customers.
HV test, or high voltage test, is conducted to check insulation integrity and electrical safety of the product.
Air leak test is performed to verify the sealing integrity of the product, ensuring no leaks that could compromise performance or safety.
These tests are required for customers to guarantee that the prod...
Quality of insulation can be controlled through proper material selection, installation techniques, and regular inspections.
Selecting high-quality insulation materials with appropriate R-values for the specific application
Ensuring proper installation techniques are followed to minimize gaps and air leaks
Conducting regular inspections to check for signs of wear, damage, or moisture intrusion
Using thermal imaging technol...
HST stands for Heat Shrink Tubing, used in wire harness for insulation and protection.
HST is a type of tubing that shrinks when heat is applied, providing insulation and protection to wires in a harness.
It helps in preventing short circuits, abrasion, and moisture damage.
HST is commonly used in automotive, aerospace, and electronics industries.
Examples of HST brands include 3M, TE Connectivity, and Panduit.
A thermistor is a type of resistor whose resistance changes significantly with temperature. There are two main types: NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient).
Thermistors are commonly used in temperature sensing applications.
NTC thermistors have a negative temperature coefficient, meaning their resistance decreases as temperature increases.
PTC thermistors have a positive tempera...
EMC testing is the process of evaluating and verifying the electromagnetic compatibility of electronic devices.
EMC testing ensures that electronic devices do not interfere with each other's operation
It also ensures that electronic devices are not susceptible to interference from external sources
Common EMC tests include radiated emissions, conducted emissions, and immunity testing
EMC testing is important for compliance ...
Ferrite core is a magnetic core made of ferrite material used in electronic components for its high magnetic permeability and low electrical conductivity.
Ferrite core is commonly used in transformers, inductors, and electromagnets.
It helps increase the inductance and efficiency of electronic components.
Ferrite cores are also used in noise suppression filters to reduce electromagnetic interference.
They are preferred ove...
EV stands for Electric Vehicle, which is a vehicle that runs on electricity instead of gasoline.
Types of EVs include Battery Electric Vehicles (BEVs), Plug-in Hybrid Electric Vehicles (PHEVs), and Hybrid Electric Vehicles (HEVs).
BEVs run solely on electricity stored in batteries and do not have a gasoline engine.
PHEVs have both an electric motor and a gasoline engine, allowing them to switch between electric and gasoli...
A parabolic equation is a second-degree polynomial equation in the form y = ax^2 + bx + c, where 'a' is the coefficient of the x^2 term.
A parabolic equation is a type of quadratic equation that forms a U-shaped curve when graphed.
The coefficient 'a' in a parabolic equation determines the direction and width of the parabola. A positive 'a' value opens upwards, while a negative 'a' value opens downwards.
For example, the ...
