How to ensure safety during the measurement process of measuring transformer?
Release Time : 2025-01-15
In the power system, transformer is a key equipment, and its performance and status monitoring are crucial. Measuring transformer is an important means to evaluate its performance and detect potential faults. However, the safety issues in the measurement process cannot be ignored. This article will discuss the key measures to ensure safety during the measurement process of measuring transformer.
First of all, ensuring the safety of the measurement environment is the top priority. Before measurement, the measurement site should be thoroughly checked to ensure that there are no debris and grounded objects, and the environment around the transformer is kept clean. At the same time, obvious warning signs should be set up to prevent unauthorized personnel from entering the measurement area. During the measurement process, operators must wear insulating gloves and insulating shoes and use insulating tools to prevent electric shock accidents.
Secondly, it is crucial to choose suitable measuring instruments and equipment. Measuring transformers should use instruments that meet the voltage level requirements to ensure that the range and accuracy level meet the measurement requirements. At the same time, the grounding of the instruments and equipment should be reliable to prevent the risk of electric shock caused by poor grounding. Before measurement, the instrument and equipment should be functionally checked to ensure that they are in good condition.
During the measurement process, the operating procedures should be strictly followed. Operators should be familiar with the performance and technical data of the transformer and operate strictly according to the measurement steps. Before measurement, the transformer must be powered off and the measurement can only be carried out after it is verified that there is no voltage. During measurement, a special measuring line should be used to connect the instrument and the device under test to avoid wire entanglement and ensure the effectiveness of the measurement. At the same time, the operator should stand on an insulating pad to keep a safe distance from the live parts.
In addition, for oil-immersed transformers, attention should be paid to the control of oil temperature during the measurement process. Too high or too low oil temperature may affect the accuracy of the measurement results and even damage the transformer. Therefore, the oil temperature should be adjusted to an appropriate range before measurement, and the change of oil temperature should be continuously monitored during the measurement process.
Finally, safety measures after the measurement are equally important. Before disconnecting the measurement connection line, the transformer should be discharged to ensure that the residual charge will not cause harm to personnel. At the same time, the measuring instruments and equipment should be cleaned and maintained for the next use.
In summary, the safety measures for measuring transformers during the measurement process include ensuring the safety of the measurement environment, selecting appropriate measuring instruments and equipment, strictly abiding by the operating procedures, paying attention to the control of oil temperature, and safety measures after the measurement. The implementation of these measures will help ensure the safety and accuracy of the measurement process and provide strong guarantees for the stable operation of the power system.
