For power grid operation and maintenance units, the procurement of lightning impulse voltage generators has never been a one-time deal. How to perform daily maintenance after purchasing the equipment, who is responsible for annual inspections, and who should be contacted for repairs when problems arise - these issues that run through the entire lifecycle of the equipment directly affect whether the equipment can operate stably for a long time and whether the test data is always accurate and reliable.

Wuhan UHV Power Technology Co., Ltd. has been deeply involved in the field of high-voltage electrical measurement for nearly 22 years. Its UHV series lightning impulse voltage generator test device has not only won market recognition for its excellent technical performance, but also has a maintenance and calibration system covering the entire life cycle of the equipment, allowing power grid operation and maintenance units to truly achieve "buy with confidence, use with ease, and manage with ease".

Daily maintenance follows a systematic approach: cleaning, inspection, and recording are all essential

The daily maintenance of high-voltage testing equipment is the foundation for ensuring long-term stable operation of the equipment. Wuhan UHV has developed a standardized daily maintenance process through long-term customer service.

In terms of cleaning and maintenance, keeping equipment clean is the primary task of daily maintenance. Regularly wipe the surface of the equipment with a clean, lint free cloth to remove dust and dirt, but avoid water or cleaning agents from entering the interior of the equipment. For each connection part of the device, it is necessary to ensure that the connection is firm and the contact is good.

In terms of component inspection, regularly check vulnerable components such as high-voltage silicon stacks, capacitors, fans, etc., to see if there are any signs of damage or aging, and replace them in a timely manner. When not in use for a long time, the battery of the current collector should be removed, and the battery must be replaced at least once a year. 

In terms of ledger management, establishing a comprehensive equipment ledger is the key to standardized management. Record equipment number, purchase date, calibration records, and maintenance history. Paper records and electronic data are synchronously saved, and electronic data is organized into folders based on device numbers for easy historical comparison and querying. The test data should be compared with the factory test data and historical data, and the deviation should not exceed the specified percentage to be considered qualified.

Annual verification is guaranteed: timely submission for inspection, standardized calibration, and traceable data

The accuracy of high-voltage testing equipment is directly related to the reliability of the test results. According to the metrological verification regulations, high-voltage testing equipment should be sent for inspection once a year, and some units adjust it to be calibrated every six months based on the frequency of use.

The first step in the verification process is to check whether the calibration label of the equipment is within its validity period. If the accuracy of the device deviates after long-term operation and the user has very strict requirements for accuracy, software calibration can be performed on the device. Calibration work requires high-precision measuring instruments or sending them to authoritative departments for calibration.

Warranty and maintenance promise: one year free, lifetime service, and fast response

The quality assurance and maintenance services of equipment are the most concerned after-sales guarantee content for power grid operation and maintenance units.

Wuhan UHV strictly adheres to the warranty commitment: within one year from the date of product purchase, free factory repair services will be provided for any quality issues that are not caused by human factors. If the product has defects for more than one year, the company still provides professional repair services.

In terms of response speed, the company guarantees to provide telephone guidance to assist customers in troubleshooting simple equipment malfunctions. For problems that require on-site resolution, the company has a professional after-sales service team that can provide timely technical support and troubleshooting services to users. Whether it's equipment installation and debugging, user training, or later maintenance, we can achieve rapid response and efficient solutions.

For power grid operation and maintenance units, purchasing a lightning impulse voltage generator is not only a testing instrument that can output standard waveforms, but also a full lifecycle management and maintenance system from daily maintenance to annual calibration, from fault repair to technical training. Wuhan UHV provides standardized daily maintenance procedures for equipment management, annual inspection services covering the whole country to ensure accuracy, and a "one-year free, lifelong service" warranty commitment to ensure worry free maintenance. With three dimensions and one system, the surge voltage generator of the power grid operation and maintenance unit truly achieves "buy with confidence, use with ease, and management with ease".
