वर्तमान ट्रांसफार्मर मुख्य रूप से विभिन्न अनुप्रयोगों में विद्युत धाराओं को मापने और निगरानी के लिए डिज़ाइन किए गए हैं। हालांकि, वोल्टेज ट्रांसफॉर्मर के संयोजन के साथ उपयोग किए जाने पर उनका उपयोग उच्च वोल्टेज अनुप्रयोगों तक बढ़ाया जा सकता है।

In high voltage systems, measuring the current directly can be challenging and unsafe due to the high voltages involved. Therefore, current transformers are employed to step down the high currents flowing through the system to a safe and manageable level. The stepped-down current is then accurately measured and monitored using standard measuring instruments, protection devices, or control systems.

When it comes to measuring high voltages, current transformers alone are not sufficient. In such cases, they are used in combination with voltage transformers. Voltage transformers, also known as potential transformers, are specifically designed to step down high voltages to a lower, measurable level.

By combining the outputs of a current transformer and a voltage transformer, it becomes possible to accurately measure both the current and voltage in a high voltage circuit. The stepped-down current from the current transformer and the stepped-down voltage from the voltage transformer are synchronized to represent the actual values of the high voltage and high current in the system.

This combined measurement of current and voltage is essential for various purposes in high voltage applications, including metering, protection, and control. For example, in a power transmission system, the current and voltage measurements obtained through current and voltage transformers are used for power quality analysis, load monitoring, fault detection, and protection coordination.

By utilizing current transformers in conjunction with voltage transformers, high voltage systems can benefit from accurate measurements, reliable protection, and effective control. It allows for the monitoring of high voltage parameters within safe and manageable ranges, ensuring the integrity and efficiency of the electrical system.

It's important to note that the selection and installation of current and voltage transformers in high voltage applications should be performed in accordance with industry standards and guidelines. Proper sizing, insulation, and calibration are crucial to ensure accurate measurements, reliable operation, and the overall safety of the system.

In summary, current transformers, in combination with voltage transformers, can be used in high voltage applications to measure and monitor both the current and voltage. This combined measurement enables accurate analysis, metering, protection, and control, ensuring the safe and efficient operation of high voltage electrical systems.
