BS EN 60835-2-7:1995 is a European standard that specifies methods for measuring the performance characteristics of inductive voltage transformers used for electrical power measurement. The standard applies to inductive voltage transformers used in high voltage electrical power systems, typically with a rated frequency of 50 Hz or 60 Hz.
The standard specifies a range of performance tests that can be used to evaluate the accuracy and other characteristics of inductive voltage transformers. These tests include:
Ratio measurement to determine the transformer's voltage ratio.
Phase displacement measurement to determine the transformer's phase angle accuracy.
Accuracy measurement to determine the transformer's accuracy class.
Temperature rise measurement to determine the transformer's ability to withstand heat.
The purpose of BS EN 60835-2-7:1995 is to ensure that inductive voltage transformers used for power measurement meet the necessary performance requirements for their intended use. The standard provides guidelines for preparing test samples and conducting the tests, and also specifies the acceptance criteria for each test. By testing inductive voltage transformers to this standard, manufacturers can ensure that their products meet the necessary performance standards, and users can be confident in the accuracy and reliability of the transformers they use for power measurement in high voltage electrical power systems.
