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
Why does a keep transistor increase HL propagation delay? Read More »
Introduction A capacitor plays a key role in electronic components, helping to store and manage voltage within a circuit. Whether dealing with electrolytic or non-electrolytic types, knowing how to test a capacitor is important to ensure they function properly. Over time, these parts may weaken, affecting device performance. Regular testing helps maintain efficiency and regulate
What is an oil surge relay? An Oil Surge Relay (OSR) is an essential auxiliary device used in oil-immersed transformers to protect against potential damage during operational failures. Positioned strategically between the on-load tap changer (OLTC) tank and its conservator, the OSR ensures that any surge in oil pressure resulting from internal arcing is quickly
Introduction When choosing the right batteries, it is important to have a clear understanding of their differences. Both AA and AAA batteries are commonly used in various devices, but they vary in size, capacity, and application. While AA batteries have a larger form and higher power, AAA batteries are compact and preferred for small gadgets
Introduction Reactor reactance is a critical parameter in electrical power systems, representing the opposition to current flow in a reactor due to its inductive properties. It is measured in ohms and is directly proportional to the frequency of the AC system and the inductance of the reactor. In AC power systems, reactance plays a vital
