The ZWLPC Online Particle Counter stands out for fluid cleanliness monitoring due to five main factors: 1) Built-in support for 7 global standards including ISO 4406 and NAS 1638; 2) A broad detection range from 1um to 1000um with high accuracy; 3) Strong environmental adaptability (handling up to...

In the petroleum, chemical, and power industries, evaluating the quality of lubricating oil is a critical daily task. The Viscosity Index is a key parameter that indicates how the oil’s viscosity changes with temperature fluctuations. However, traditional testing methods can be...

Power transformers are one of the most capital-intensive assets in power grid systems, making their regular maintenance and condition diagnosis crucial. Among numerous diagnostic methods, Sweep Frequency Response Analysis (SFRA) has become an industry-recognized standard test due to its high sensitivity to winding deformations (such as twisting, displacement, bulging, etc.). However, on-site live maintenance teams […]

Operating an online particle counter like the ZWLPC involves three main phases: proper installation with flow/pressure regulation, precise parameter configuration (including standards like ISO 4406 or NAS 1638), and conducting the test after a 10-minute preheat and a minimum 100 mL pipeline flush....

In industries such as petroleum, chemical manufacturing, power generation, and pharmaceuticals, even a microscopic amount of water can compromise product quality or lead to catastrophic equipment failure. For instance, detecting moisture in transformer oil is critical to maintaining the insulation...

Testing high-voltage circuit breakers in substations is a critical task that demands precision, safety, and reliability. When dealing with systems up to 500KV, engineers face significant challenges, including severe electromagnetic interference, complex wiring setups, and the need to test various...

Accurately measuring the Transformer Turns Ratio (TTR) and connection group is a crucial step during the production, commissioning, and regular maintenance of power transformers. To comply with the IEC 60076-1 standard, test engineers must gather precise voltage ratio data and diagnose various...

You might look at a sample of industrial oil and see a perfectly clear, amber liquid. However, to your machinery, that same fluid could be hiding invisible boulders grinding away at your bottom line. Just like sand trapped in a clock's delicate gears, microscopic contaminants cause massive...

Insulating oil plays a vital role in electrical equipment. It insulates and cools transformers, ensuring efficient operation. However, the quality of this oil can degrade over time. One key indicator of oil quality is interfacial tension (IFT). Low interfacial tension suggests contamination...

In power systems, transformer oil does more than just cool the equipment; more importantly, it provides critical electrical insulation. The Breakdown Voltage (BDV) test is the most direct way to measure the oil’s ability to withstand electrical stress. When performing BDV tests according to...
