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.

“GR-487, Issue 5, Generic Requirements for Electronic Equipment Cabinets provides the latest criteria
(2016) for analyzing Electronic Equipment Cabinets used in a variety of outside plant environments and applications, including wireless.

It includes proposed functional design criteria, generic mechanical, and environmental requirements, desired features, and  performance tests. Issue 5 was developed with the input of more than a dozen national and international users, suppliers, manufacturers, and installers of Electronic Equipment Cabinets.
