Overview
The neutral point capacitance method is used to measure the capacitance current of the distribution network. The test results are accurate, stable, and reliable, and are not affected by other operating conditions. It is safe, simple, and fast
Product Details
Product IntroductionProduct Introduction
According to China's power regulations, when the capacitance current of 10kV and 35kV systems is greater than 30A and 10A respectively, arc suppression coils should be installed to compensate for the capacitance current. This requires measuring the capacitance current of the distribution network to determine whether to install arc suppression coils.
In addition, the coordination between the ground capacitance of the distribution network and the parameters of PT can generate PT ferromagnetic resonance overvoltage. In order to verify whether PT resonance will occur in the distribution system and what kind of resonance will occur, it is also necessary to accurately measure the ground capacitance value of the distribution network.
The methods for measuring the capacitance current of the distribution network include direct method with single-phase metal grounding, indirect measurement method with external capacitance, and signal addition method with PT open triangle. However, the most popular and frequently used method on site is still the neutral point capacitance method.
The HTCI-V fully automatic capacitance current tester uses the neutral point capacitance method to measure the distribution network capacitance current. The tester adopts a large screen LCD display and a Chinese menu. After taking safety measures and setting the instrument parameters in advance, there is no need to touch and operate the instrument, making this work safe, simple, and fast. The test results are accurate, stable, and reliable, and are not affected by other operating conditions, especially when the system is unbalanced.
