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

Posted by Protec Tech Team on

Vanguard VBT-80 Vacuum Bottle TesterVacuum 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.

Vacuum bottle testers are part of a preventive maintenance program for ensuring the integrity of these vacuum sealed bottles that encase the contacts for circuit breakers and other electrical switching mechanisms in our power systems. If your job requirements include verifying the health of vacuum bottle contacts check out Vanguard vacuum bottle test equipment. The VBT-60VBT-80 and VBT-80P are some of the most popular vacuum bottles test equipment on the market. These testers have a continuously adjustable output voltage for testing various types of interrupters. The VBT-60 has a maximum output of 60 kV while the VBT-80 and VBT-80P have a maximum output voltage of 80 kV. Read on to learn more about the differences on features of each tester.

Vanguard VBT-60 Vacuum Bottle Tester

The VBT-60 is a microprocessor-based tester that is lightweight, portable and reliable which makes it suitable for shop and field applications. It features an automated test feature to save you time and effort in testing. It also has a a protection circuit that shuts off the test current if a flash-over condition occurs.
