Electric safety is the first priority. KV Hipot Power Test Equipment Co.,ltd is always attach importance to personal safety. KV Hipot organized basic electrical safety training course on Tuesday . Our engineers explains the basic electrical knowledge and share some experience on debugging and testing onsite .
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.
The maintenance of electrical equipment is a key point that cannot be ignored in the entire production work. It not only provides guarantee for the production of enterprises, but also vigorously promotes the development of electrical equipment in China. Therefore, for now, it is of great significance to study the preventive daily maintenance of electrical equipment.
Batteries are the core of critical DC power system , which can provide stable and uninterrupted backup power in various industry. In the event of power failure in the power facilities or transformer substation , the bacup batteries are the last guard of DC power system . It is crucial to identify batteries state of health before they fail.
It is a diffcult process to choose the right and suitable battery test equipment for your different application . Here are some test equipment for your battery testing for checking battery the state of health.
What is VLF testing ?
VLF testing is a method to test Medium voltage and high voltage cable for verifying the cable insulation . VLF diagnostic testing is a withstand voltage test usually carried out at a frequency of between 0.1 Hz and 0.01 Hz rather than 50/60 Hz.
Series resonance is related with circuit and series connection. It is a resonance condition that usually occurs in series circuits. Generally, A series resonance test system is classified into two types regulating the induction and regulating frequency. It is composed by an exciting transformer, variable frequency power, capacitive voltage divider and reactor.
Hipot test is short for high potential test and it is also called dielectric withstand test or pressure test or insulation test. Hipot test is a nondestructive test that determines the effectiveness of its insulation for withstanding over transient high voltage. It is high voltage test that is applied to all devices to ensure electrical insulation material is adequate.
Proceeding with the hipot test is helpful to find the possible defects and Inadequate creepage and clearance distances during the manufacturing process.
