A PPM meter, or parts per million meter, is a device or instrument used to measure the concentration of a substance in a solution or mixture. Parts per million (PPM) is a unit of measurement that expresses the ratio of the number of parts of a particular substance to one million parts of the entire … Read more
An Air Handling Unit (AHU) plays a crucial role in creating and maintaining a dustproof environment in facilities such as cleanrooms, laboratories, data centers, or any area where the control of airborne particles and contaminants is paramount. Here’s how AHUs are used to achieve a dustproof hall: Components of Air Handling Unit (AHU) An Air … Read more
An over voltage relay is an indispensable protective device used to monitor and respond to voltage spikes or surges in electrical systems. It functions by detecting when the voltage level surpasses a predetermined threshold, triggering the relay to initiate a specific action, such as opening a circuit breaker or disconnecting a load. Over voltage relays … Read more
An under voltage relay is an essential protective device used in electrical systems to monitor and respond to voltage fluctuations. It is designed to detect when the voltage level falls below a predetermined threshold, signaling the relay to initiate a specific action, such as opening a circuit breaker or disconnecting a load. Under voltage relays … Read more
A toroidal transformer is a type of power transformer known for its distinctive toroid shape, resembling a donut or bagel. Its core is crafted from a continuous strip of high-grade silicon steel, wound into a circular form, facilitating the wrapping of primary and secondary windings around it. The circular configuration ensures maximum magnetic coupling and … Read more
A tap-changing transformer, also known as an on-load tap changer (OLTC) transformer, is a specialized type of power transformer that allows for the adjustment of its winding turns ratio while it is energized and under load. This unique capability enables the transformer to regulate the output voltage and compensate for voltage fluctuations that occur in … Read more
V/F control is a popular technique used to maintain a constant ratio of voltage to frequency (V/F) applied to an induction motor’s stator. This control strategy ensures a stable magnetic flux within the motor, which leads to smoother operation and better efficiency. The primary goal of V/F control is to adjust the amplitude of the … Read more
