The new dual-purpose instrument combines high-voltage insulation testing up to 20 GΩ with comprehensive electrical measurement capabilities for field electricians.

Insulation failure is a leading cause of electrical fires and system downtime, often occurring silently before any visible ...

The street scene shows damage caused by an explosion in a manhole as a result of gases generated by a low-voltage arcing fault. North America, according to statistics published by the IEEE Insulated ...

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

Insulation resistance testing is a simple yet critical preventive measure that can significantly lower your maintenance costs. You may be familiar with the role insulation resistance testing plays in ...

An AC resonant test system is designed to generate high alternating voltage by forming a resonant circuit between the reactor and the test object. By operating at or near resonance, the system can ...

Testing insulation is an important way to qualify a new installation. Testing also protects and prolongs the life of electrical systems and motors. Over the years, electrical systems are exposed to ...

Hipot testers are used to measure the leakage current and insulation resistance between all components and connections, verify solid ground connections, and test ground bonds. These tests include the ...

The measurement engineer can view the values from tan δ and partial-discharge testing directly in the cable test van. Clear representation helps to detect severe defects or locate partial discharges ...

Insulation problems are to blame for around 30% or more of motor failures – meaning that electrical motor testing should be a larger part of every condition monitoring regime. Mike Teska, Product Line ...
