Circuit Breaker Operating Mechanism MCB Usage & Principle

What is MCB? MCB or Miniature Circuit Breakers is a mechanical switching device which is capable of making, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time and automatically breaking currents under specified abnormal circuit conditions such as those of short circuit. So we can say that MCB… Read More »

ELCB Earth Leakage Circuit Breaker

What is an ELCB? An Earth Leakage Circuit Breaker (ELCB) is a safety device used in electrical installations with high earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use… Read More »

Construction Usage & Operating Principle of Light Dependent Resistors LDR’s

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 »

HVDC & AC TRANSMISSION & DISTRIBUTION SYSTEM FOR ELECTRICAL ENERGY

Generally there are two power transmission and distribution systems that are used to transmit electrical energy i.e. HVDC or High Voltage Direct Current transmission system and HVAC or High Voltage Alternating Current transmission system. Now let’s see the advantages and disadvantages of both power distribution systems. COMPARISION OF HVAC & HVDC SYSTEMS HVAC transmission is… Read More »
