We all know that voltage transformers (PT) cannot be short circuited, and current transformers (CT) cannot be open circuited. Once the voltage transformer is short circuited or the current transformer is open circuited, it can cause damage or danger to the transformer. In principle, we all know that voltage transformers…

VLF HV Generator is a type of power equipment used to generate ultra-low frequency and high voltage. It is usually widely used in the testing and diagnosis of power systems, insulation material testing, and other related fields. Ultra low frequency (VLF) signals refer to electrical signals in the frequency range…

The oil chromatography analyzer mainly utilizes the differences in boiling point, polarity, and adsorption properties of substances to achieve the separation of mixtures. After the sample to be analyzed vaporizes in the gasification chamber, an inert gas (i.e. carrier gas, also known as mobile phase) is introduced into the chromatographic…

Fully automatic capacitance and inductance tester, abbreviated as capacitance and inductance tester. The fully automatic capacitance and inductance tester adopts a bridge circuit structure, with standard capacitors and the tested electrical container as the two arms of the bridge circuit. When measuring the capacitance value of the capacitor, close the…

There may be several reasons why the DC high-voltage generator cannot add high voltage:1. Power issue:The DC high-voltage generator requires a stable and reliable power supply to operate normally. If the power supply voltage is unstable, fluctuates significantly, or the power supply current is insufficient, it may cause the DC…

Dielectric loss refers to the conductivity loss and polarization loss generated by transformer oil under the action of alternating power plants. This type of loss can lead to a decrease in insulation strength and heat transfer performance, ultimately leading to problems such as overheating, damage, and breakdown of the transformer.…
