What is BS EN 60060-2 - Measuring systems for high-voltage testing about?
BS EN 60060-2 is an International Standard on high-voltage test techniques.
BS EN 60060-2 is about complete measuring systems, and their components, used for the measurement of high voltages during laboratory and factory tests with direct voltage, alternating voltage, and lightning and switching impulse voltages as specified in BS EN 60060-1.
The limits on uncertainties of measurements stated in BS EN 60060-2 apply to test levels stated
in IEC 60071-1:2006. The principles of BS EN 60060-2 apply also to higher levels, but the uncertainty may be greater.
BS EN 60060-2 provides you with the following:
- Defines the terms used
- Describes methods to estimate the uncertainties of high-voltage measurements
- States the requirements which the measuring systems shall meet
- Describes the methods for approving a measuring system and checking its components
- Describes the procedures by which the user can show that a measuring system meets the requirements of BS EN 60060-2, including the limits set for the uncertainty of measurement
Note: For measurements during on-site tests see BS EN 60060-3.
Who is BS EN 60060-2 - Measuring systems for high-voltage testing for?
BS EN 60060-2 on measuring systems for high-voltage testing is relevant to:
- Manufacturers and designers of high voltage testing equipment
- Manufacturers of voltage transformers
- Manufacturers of measuring instruments
- Electrical engineers
- Testing laboratories and authorities
- Quality control personnel
- Calibration laboratories
- Manufacturers of electrical equipment / tools / machines / appliances
Why should you use BS EN 60060-2 - Measuring systems for high-voltage testing?
A measuring system is a complete set of devices suitable for performing a high-voltage measurement. Software, used to obtain or calculate measuring results, also forms a part of the measuring system.
Every approved measuring system in accordance with BS EN 60060-2 undergoes initial testing, followed by performance tests and performance checks throughout its service life. The initial tests consist of type tests (performed on a component or system of the same design) and routine tests (performed on every component or system).
BS EN 60060-2 helps in assigning the scale factor in the performance test by calibration. The user shall apply tests given in BS EN 60060-2 to qualify their measuring system(s). Alternatively, any user may choose to have the performance tests made by a National Metrology Institute or by a calibration laboratory accredited for the quantity to be calibrated. In all cases, the user shall include the test data in the record of performance.
The record of performance comprises at least the following information:
- General description of the measuring system
- Results of type and routine tests on the converting device, transmission system(s) and measuring instrument(s) and, if performed, on the measuring system
- Results of subsequent performance tests on the measuring system
- Results of subsequent performance checks on the measuring system
The assigned scale factor of the measuring system is determined by calibration according to the specified performance tests. The assigned scale factor is a single value for the assigned measurement range.
BS EN 60060-2 contributes towards better testing techniques and accuracy. This helps manufacturers to innovate and provide customers with high-quality, long-lasting products.
