Different Types of Conduit Wiring
Conduit wiring refers to a type of electrical wiring where the electrical wires are encased in a conduit, which is a tube made of metal or plastic. The conduit protects the wires from damage...
Transformer On-load (OLTC) and No-load (NLTC) Tap changers
A tap changer is a device that is used to change the voltage of an electrical transformer. A transformer is a device that uses electromagnetic induction to convert electrical energy from one voltage level...
What is the function of a silica gel breather in power transformers?
A breather is a device used in a transformer to allow air to flow in and out of the transformer tank, while also preventing the ingress of moisture and dust. The breather typically consists...
Why DC series motor should not be started on no-load ?
A DC series motor is a type of electric motor that operates on direct current (DC) and has its field windings connected in series with its armature windings. This type of motor is characterized...
How BLDC is different from normal dc motor?
A brushless DC motor (BLDC) is a type of DC motor that uses electronic commutation instead of a mechanical commutator to switch the current flowing through the windings. This allows for higher efficiency, longer...
What is NCT or Neutral Current Transformer ?
A neutral current transformer (NCT) is a type of current transformer that is used to measure the neutral current in a three-phase electrical system. It is typically used in applications where the neutral point...
What is a Capacitor Bank?
A capacitor bank is a group of capacitors connected together in a specific configuration, typically in parallel or in series. Capacitor banks are commonly used in electrical power systems to improve the power factor...
What are different types of transformer cooling methods?
Different types of transformer cooling methods are available and those methods are mainly chosen based on the transformer power ratings. Dry-type Air Natural (AN) Air Forced (AF) Oil-immersed Oil Natural Air Natural (ONAN) Oil...
Common types of Switches used in electrical wiring
An electric switch is a component that can open or close an electrical circuit. That is, it engages or disengages an electric contact between terminals of a conductive circuit to provide a path for the electric current...
