In the vast system of the entire power industry, multifunctional calibrators play an irreplaceable and crucial role. Starting from the power generation link, the source of power production, various generator sets rely on a large number of sensors to monitor their operating status in real - time during operation. For example, the temperature sensor is responsible for measuring the temperature of key components of the generator set. Once the temperature rises abnormally, it may indicate serious malfunctions inside the equipment and even trigger safety accidents. The pressure sensor is used to monitor the pressure of media such as steam in pipelines to ensure that the pressure is maintained within a reasonable range, so as to guarantee power generation efficiency and equipment safety. Through high - precision calibration technology, multifunctional calibrators can carefully adjust the measurement accuracy of these sensors, making the measurement data of parameters such as temperature and pressure as accurate as possible, thus laying a solid foundation for the stable operation of the generator set.
In the process of power transmission and transformation, the safe and stable operation of the power system is even more inseparable from multifunctional calibrators. The relay protection device, as the "guardian" of the power system, is of self - evident importance. When abnormal situations such as short - circuits and overloads occur in the power system, the relay protection device needs to make accurate judgments within an extremely short time and act quickly to cut off the faulty line to avoid the expansion of the accident scope. When calibrating the relay protection device, the multifunctional calibrator will simulate various complex power failure scenarios, such as different types of short - circuit faults and voltage mutations, and detect key indicators of the relay protection device, such as action accuracy and response time. For example, during the regular maintenance of a large - scale substation, technicians followed strict calibration procedures and used a multifunctional calibrator to calibrate the key relay protection equipment in the station one by one. During the calibration process, by simulating a phase - to - phase short - circuit fault on a 10kV line, it was found that the action time of one relay protection device exceeded the specified range. The technicians immediately debugged and calibrated the device, promptly eliminated potential fault hazards, and successfully avoided a possible large - scale power outage accident, ensuring the stable power supply in the entire region.
