Accurate Partial Discharge Measurements Begin with Proper Calibration Partial discharge (PD) testing plays a critical role in evaluating the condition of high-voltage insulation systems. From transformers and power cables to rotating machines and switchgear, detecting partial discharge activity early helps engineers identify insulation defects before they develop into costly equipment…

When purchasing an electrostatic discharge (ESD) generator, it\'s easy to focus on one specification: maximum output voltage. But choosing the right ESD simulator involves much more than selecting between 16 kV and 30 kV. Today\'s electronic devices are smaller, faster, and more sensitive than ever before, making reliable ESD testing…

In high voltage testing environments, precision is critical. Even minor inaccuracies in AC/DC measurement can impact testing reliability, equipment validation, compliance reporting, and overall operational safety. As testing requirements continue to evolve across utilities, manufacturing facilities, research laboratories, and transformer testing programs, the demand for accurate and dependable measurement solutions…

Lightning doesn’t need to strike your aircraft directly to wreak havoc. Even nearby strikes can induce surges in sensitive wiring, sending data corruption, resets, or equipment failures right through your avionics systems. For military and aerospace engineers, these “invisible threats” aren’t hypothetical; they’re a real risk in every flight environment.…

When high voltage equipment fails, it rarely does so without warning. Transformers, bushings, and cables don’t just collapse overnight; they drift. Quietly. Gradually. A little moisture. A bit of contamination. Aging insulation is doing what time always asks of it. The real question isn’t if issues develop. It’s whether you…

The Accreditation Ecosystem: What It Really Means Accredited calibration operates within a structured system designed to ensure measurement results are reliable, consistent, and internationally recognized. At the center of this system is ISO/IEC 17025, the global standard defining technical and quality requirements for calibration laboratories. Accreditation bodies continuously assess and…

There was a time when having equipment “calibrated” was enough – a certificate, a sticker, a checked box. But today’s testing and measurement environments demand more than reassurance; they demand proof. Tighter regulations, global supply chains, and increasingly knowledgeable auditors have raised the bar on what “acceptable” really means. Accredited…

When insulation systems, transformers, or cables are stressed with impulses, you don’t want guesswork; you want clarity. Enter the Haefely HiAS 744, a cutting-edge impulse analyzing system designed to capture, analyze, and make sense of high voltage phenomena with unmatched fidelity. Compact, versatile, and engineered for testing laboratory applications, the HiAS 744…

Electromagnetic interference (EMI) can disrupt even the most sophisticated systems, yet shielded cameras act as vigilant sentinels, monitoring both the visible and invisible aspects of our environments with precision and reliability. These specialized devices go beyond being mere tools; they pierce through interference to reveal the truth with steady, reliable…

Transformers serve as critical components in electrical power systems, and their operational integrity is essential for maintaining uninterrupted service across residential, commercial, and industrial sectors. Failures in transformer units can result in significant service disruptions and substantial financial losses due to widespread outages. As with all high-voltage electrical equipment, routine…
