HV Hipot Electric Co., Ltd. specializes in producing series resonance (also known as cable withstand voltage testing equipment). Next, we will share with you the operation introduction of series resonance.
In power preventive testing, the series resonance test device is a testing equipment used to test the insulation performance of electrical equipment. In fact, the measurement principle is to fully utilize the introduction and practice of series resonance circuits, and to combine the broad matching of capacitance and inductance with the production process of modular circuits to form a power preventive testing equipment.
1. Introduction to Series Resonance Configuration Scheme
The configuration plan ultimately boils down to the matching of capacitors and inductors. With a certain capacitance, the resonant frequency should be adjusted to be as close to the power frequency as possible by adjusting the reactance. The configuration plan has two stages. The first stage is that in the initial design, we need to comprehensively consider the capacitance size and voltage level of the test object to determine the installed capacity of the series resonance test device and the logic of the reactor combination. We need to take into account both large capacity equipment on site and high voltage equipment, as well as consider portability, matching degree, etc. The second stage is how to match it when using it on site. Usually, HV Hipot Electric Co., Ltd. series resonance products are randomly distributed with product information, which specifies the specific configuration methods for the test object you considered when designing, and these configuration methods are all included. This is HV Hipot Electric Co., Ltd. calculated method, Before HV Hipot Electric Co., Ltd. experiment, you only need to carry the relevant equipment as required, greatly reducing HV Hipot Electric Co., Ltd. work time and workload.

2. Operation method for series resonance test of power cables
After connecting the wires as required, perform full field isolation and protection before starting the test. It should be noted that when testing the cable, if you only test one phase, you need to short-circuit the unused test phase to ground and ensure sufficient safety distance. Series resonance belongs to high-voltage and high-capacity testing equipment, and must be strictly implemented according to specifications and regulations when using it.
After turning on the power and loading the Windows interface, guide to the main operation interface. The interface of the series resonance test device has three operation modes. If you have no special requirements, we recommend using the “fully automatic” operation mode, which is both safe and convenient. Just set the target voltage value, protection voltage value, and withstand voltage duration. Click the start button, the high voltage indicator light will prompt the voltage status, and the voltage divider will collect the current voltage value. When the resonance frequency changes to the test frequency, the “resonance voltage” will be generated.
