The DC grounding locator for ultra-high voltage production is a new generation tester. It can be applied to any voltage level of DC system, equipped with high-precision detection clamp meters, greatly improving the detection range and resistance through efficient processing of multiple signals; The algorithm and fuzzy control calculation theory used represent the superiority of the tested insulation branch in numerical form, fully demonstrating the effectiveness of artificial intelligence; They have accurate judgment in determining the location of the grounding point, and can indicate the location and direction of the grounding point every time they detect it.
DC leakage currentTaking system security as the primary premise, we strictly follow the requirements of industry standards and conduct reliable low-frequency signal detection. We have also applied it extensively on site without any impact on the system.
The DC system of power plants and substations provides power for control, protection, signaling, and automatic devices. The safe and continuous operation of the DC system is of great importance in ensuring power generation and supply. Due to the floating and ungrounded nature of the DC system, if two points are grounded, it may cause the above-mentioned devices to malfunction or refuse to operate, resulting in major accidents. Therefore, when a grounding occurs, it is necessary to accurately and quickly detect the grounding point while ensuring the normal power supply of the DC system, eliminate the grounding fault, and avoid the potential harm caused by two-point grounding.
DC leakage currentUsed to accurately locate the grounding point of the DC system in power plants and substations under continuous power supply. All types of grounding faults can be quickly located with good accuracy.
