Mastering High Voltage: The Importance of Accurate Test Equipment

This whitepaper underscores that precise calibration of high-voltage test gear — especially when measuring 1 kV–150 kV systems — is essential for safety, reliability, and regulatory compliance. It details measurement techniques (voltage dividers, step-down transformers, etc.), the impact of environmental and connection factors on accuracy, and why traceable calibration (e.g. to NIST / A2LA) is a must to ensure consistent, reliable results.
