When it comes to consumer devices, starters are one of the outstanding product lines with eye-catching designs and easy installation. However, during use, this device may encounter some problems that need to be fixed immediately to ensure smooth, stable operation and better efficiency. In particular, there will be a phenomenon of non-suction starters, which is also a common problem that many users often encounter. This article will help you understand the cause and provide specific solutions to handle this situation.

Hydraulic pumps operate based on the rotary motion provided by an electric motor or diesel engine. When operating, it has the task of sucking liquid such as oil or lubricant and pushing it continuously through the system, ensuring the entire circuit operates smoothly. Therefore, this device plays a key role in any hydraulic system.

Although LCRs, network analyzers, and specialized instruments are capable of providing accurate inductance measurements over a wide frequency range, they are not always necessary. In many practical applications, especially with circuits operating at moderate frequencies, a combination of a signal generator and an oscilloscope is a more reasonable solution.

What is breakdown voltage? Why do insulating materials lose their insulating ability? Let's learn about common breakdown types in electronic components in the article below!

In automatic control systems, unstable power supply can lead to many problems such as equipment malfunction, signal interruption or reduced component life. Especially for important devices such as PLC, sensor, relay or HMI, clean and stable current is an indispensable factor. This is also the reason why choosing the right power supply is always a top priority for engineers.

Partial discharge (PD) is an incomplete discharge that bridges the gap between two high voltage electrodes, usually occurring at points where the electric field is concentrated or the insulation material is degraded. This is an early sign of insulation degradation, which can potentially damage equipment if not detected and treated promptly.

In many electrical control systems, there are small components that have a significant impact on operating efficiency, and the contactor auxiliary contact is a typical example. Integrated to expand control capabilities and increase flexibility for the starter, the auxiliary contact not only helps monitor the status of the device but also effectively supports circuit protection functions. The following article will clarify more about the contactor auxiliary contact, let's take a look!

After a period of use, many people find that the image from the UNI-T industrial endoscope is no longer as sharp as before. So what is the cause: the sensor, the endoscope or the way it is used? Let's find out with EMIN to know how to recognize and fix this situation properly.

Water pressure is the force exerted by a liquid on the walls of a pipe or the surface of a container, often occurring in water supply and drainage systems, boilers or hydraulic equipment. To effectively control these systems, equipment is needed that can accurately measure and compare pressure differences.
