Latest News From Vacuum Interrupters, Inc.
Our R&D has recently resulted in producing a process for reconditioning and extending the life of selected vacuum interrupters. You can veiw or download the paper presented at NETA's 2019 PowerTEST Conference entitled The Reconditioning of Vacuum Interrupters is Nearer Than You May Think.
CTVT-45 Two-In-One Instruemnt Transformer Test Set Announced
This is a unique, multi-function tester which incorporates the necessary capabilities to test both current transformers (CTs) and voltage transformers (VTs/PTs) in the field or shop. Comprehensive tests are performed in accordance with applicable ANSI and IEC test standards. Lightweight, rugged and user-friendly, the CTVT-45 sets a new standard in instrument transformer test equipment for field use.
