DC Insulation Testing
Diagnostic insulation testing today represents over a hundred years of constant development. When Sydney Evershed pioneered the first insulation tests in the late 19th century, the only measurable values were insulation at 500 volts and a basic continuity check. However, measurement techniques have continuously evolved to keep pace with new insulation technologies. From electronic design and household wiring to generators and power transmission systems, all different kinds of insulation must operate at a safe minimum value.

Linear Polarization Resistance (LPR) Monitoring
The electrochemical technique, commonly referred to as Linear Polarization Resistance, is the only corrosion monitoring method that allows corrosion rates to be measured directly, in real time. Although limited to electrolytically conducting liquids, the response time and data quality of this technique make it clearly superior, where applicable, to all other forms of corrosion monitoring.

Contact Resistance Test Sets
When a high current passes through a pair of mechanically independent metallic contacts, the resistance must be as low as possible. An increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Our range of micro-ohmmeters measure both steady state and dynamic low resistance values. With test currents up to 600A available, logging and trending are also available on some models. We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.
