LDR or Light Dependent Resistor which is also known as photo resistor is a device whose resistivity is a function of the incident electromagnetic radiation. SO we can say that these are light sensitive devices. Other terms which are used for LDR are photo conductors, photo conductive cells or simply photocells. Light dependent resistor (LDR) or… Read More »
Buchholz Relay Circuit is used for Transformer Protection, as we know there are many defects and dangers during the operation of power transformer that need to be addressed and necessary measures to be taken. Some of the hazards to transformer protection include overheating, over current and short circuiting etc. Another class of fault that causes a transformer… Read More »
What is a VFD? As the name describes VFD or Variable Frequency Drive is motor controller that drives an electric motor by applying the varying frequency and voltage to the electric motor that are used in the case where we need to change the speed of motors depending upon the load requirements. Other names for… Read More »
