Why do we measure transformer winding resistance ?

Each transformer is included different accessories , such as iron core , windings , coil, insulation material , tap-changers etc. The transformer windings plays a importance role during the running .

This article will introduce the knowledge about the types , the significance of transformer winding and the transformer winding test

Cruise Batteries Maintenance

The marine battery is a crucial component of a ship’s power system and serves as a vital source of power. This artclie is to the knowladge about the cruise batteries maintenance .

How do you regenerate lead acid batteries?

Battery regeneration is a process of restoring or rejuvenating the performance and capacity of a rechargeable battery that has experienced degradation or reduced efficiency over time.

Common mistakes to avoid when conducting a battery discharge test

While conducting a battery discharge test may seem straightforward, there are common mistakes that can lead to inaccurate results and potential safety hazards. In this article, we will discuss some best practices for conducting a battery discharge test and common mistakes to avoid.

What electrical transformers tests to conduct before installation

What electrical transformers tests to conduct before installation ?

Transformer dielectric test
Transformer winding resistance test
Transformer turn ratio test
Transformer insulation resistance test

Transformer capacitance & tan delta test
Transformer load loss (short circuit )and impedence test

Transformer temperature rise test

What is battery load bank ?

Battery load bank is a device that is used to test the performance and capacity of batteries by subjecting them to a simulated load, which realize the constant discharge at the set value by regulating continuously the discharge current.

What is the purpose of VLF testing?

The purpose of VLF testing is to detect any potential weaknesses or defects in the insulation of cables and equipment, which can cause electrical breakdowns and failures.

What is tan-delta test ?

Tan-delta test is also know as dielectric losss testing. Dielectric loss refers to the energy loss that occurs in a dielectric material (such as the insulation of a transformer) when an electric field is applied to it. The dielectric loss is caused by the electrical resistance of the material, which results in the conversion of electrical energy into heat.
