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.

Amphenol’s H4 connectors feature RADSOK technology, offering the highest current ratings and lowest contact resistance resulting in lower power losses and improved reliability.  They are compatible with industry-standard connectors. The upgraded connectors meet NEC 2011 requirements without the need for extra locking collars or locking sleeves.   They are RoHS-compliant and use a simple unlocking tool for easy mating and unmating in the field. The H4 is available in four different gauges including 14 AWG rated at 32A, 12 AWG rated at 40A, 10 AWG rated at 44A and 8 AWG rated at 65A.
