An electrical equipment's ability to withstand an extreme fault is a necessary engineering parameter to ensure installation safety and gain access to global markets. Direct current short-circuit tests up to 1000 Vdc provide objective data on the dynamic behavior of insulating and conducting materials subjected to intense energy stresses. The INTEK laboratory addresses this technical need by delivering operational tests and measurements essential for validating low-voltage device performance and certifying plant electrical safety.
INTEK's power infrastructure utilizes a dedicated 7.5 MVA transformer designed to maintain absolute voltage stability during current peaks. The laboratory is capable of delivering currents up to 16 kA at 1000 Vdc, covering the validation of everything from small DIN-rail components up to industrial distribution switchboards. The tests utilize high-frequency digital measurement chains for continuous monitoring of energy transients and immediate thermal impact. All test procedures are performed in compliance with current international standards, covering fundamental norms such as EN 60947, EN 60898, and North American UL 508 specifications.
Successfully passing short-circuit withstand tests eliminates structural uncertainties. The data provided by the laboratory enables design engineers to optimize material safety margins, minimizing the risk of incidents in target installations and ensuring operational reliability.
