Introduction In my years of working with transformers, I’ve realized how crucial maintenance is to ensure smooth performance across many domains. Regular oil tests and equipment testing are essential, especially when it comes to testing the condition of transformer oil, cables, and switches. One effective method that I’ve often used is the Tan Delta Test, […]

What is a Three Phase Energy Meter? A three phase energy meter plays a vital role in measuring the total power consumed across a three-phase supply. This meter is smartly constructed by connecting two single-phase meter units through a shaft, ensuring smooth operation and accuracy. The reading from both elements gives the sum of energy

When it comes to wiring solutions, casing and capping wiring are a recommended method for safe electrical setups. This system performs admirably in homes and offices, offering protection for insulated wires. The casing is a rectangular strip made of PVC, with a white or gray cap that keeps the wires securely encased. Designed for low-voltage

The Megger test is a widely used method for testing the insulation resistance of an electrical system. Over the years, its purpose has remained the same, ensuring safety by detecting any leakage or degradation in insulation. The instrument, often named a tester, applies D.C. voltage across its probes, calculating the IR value automatically. This method

The conductivity of semiconductors mainly depends on the concentration of free electrons present in the material. Unlike conductors, where large numbers of electrons move freely, or insulators, where the count is small, semiconductors have a moderate level of free charge carriers. The key difference is that in materials like germanium and silicon, valence electrons are

Introduction When dealing with electrical components, selecting the proper type of switch is important to ensure a reliable application. Among various circuits, the SPDT switch stands out due to its versatility. This switch allows a circuit to break or connect in different ways, making it suitable for multi-make and multi-break configurations. The mechanics behind its

Introduction If you’ve ever worked with electrical systems, you’ve probably encountered the terms (Normally Open) NO and NC (Normally Closed). These refer to the state of a contactor when the system’s power is off. For safety reasons, a NO contactor is designed to open the circuit, ensuring that the flow of energy stops when the

From my experience working with circuit design, I’ve noticed how a keep transistor affects signal propagation. When switching from high to low, the output signal doesn’t drop instantly; instead, it encounters resistance in the path, leading to a slowing effect. This happens because the keep transistor introduces an additional element that interferes with the discharge
