What Is the Advantage of VLF Hipot Testing?

POSTED BY Protec Tech Team

 VLF hipot —very low frequency hipot — is an AC high potential instrument used for testing the dielectric strength of insulating materials at 0.1 Hz or lower. Instead of having to perform DC testing because high potential test equipment that operates at power system frequency are large, heavy and therefore not very portable, VLF high potential testing  makes testing cables and electrical apparatus in the field more practical and economical.

The Vanguard VBT-60, VBT-80 and VBT-80P Vacuum Bottle Testers

POSTED BY Protec Tech Team

Vacuum interrupters offer several advantages over older arc extinguishing contact systems found in circuit breakers and other types of switch gear. Vacuum breakers have long mechanical and electrical operating life and excellent switching capabilities. These sealed bottles create an envelop of negative pressure that is not conducive to the formation or sustaining of electrical arcs when contacts operate under load.  Additionally, since the contacts are encased in a bottle, they are not exposed to the contaminants found in many of the environments where they are utilized. They are virtually maintenance-free and have operation counts from 5000 to 1000000 before they reach their end of life. However, even if they have long operating lives, vacuum bottles should be tested for defects to avoid problems in the electrical system.

Vanguard Test Info: Why Use a DLRO (Digital Low Resistance Ohmmeter)?

POSTED BY Protec Tech Team

If you are reading this blog, it might be because it is time to break out a Micro-Ohmmeter to ensure the reliability of electrical connections throughout your electrical power system. The Vanguard Auto-Ohm is the ideal tool to use when evaluating the integrity of electrical bonds to power system equipment, as well as the contact resistance within the electrical equipment itself.

The Test Equipment You Need for Cable Preventive Maintenance

POSTED BY Protec Tech Team

Cables are exposed to the elements like moisture, dirt and other contaminants. They are also subjected to mechanical and electrical stress during operation. This is the importance of regular testing of cables. Predictive maintenance often employs diagnostic type tests which will provide the test data necessary to prioritize the replacement of those cables before they become faulted and the source of unscheduled down time.
