美國vanguard EZCT-10電流互感器測試裝置

The Model EZCT-10 is a microprocessor-based, current-transformer test set. This rugged and portable test set measures excitation current, turns ratio and winding polarity on single- and multi-ratio current transformers. Current transformers can be tested in their field-mounted configuration, eliminating the need to remove bushings or current transformers from the host equipment.

• Perform Saturation, Ratio and Polarity Tests
• Fully Automated
• Comprehensive Graphic and Tabulated Test Reports
• Plot Multiple Saturation Curves
• Store 64 Records (of 10 Saturation Curves)
• Computer Interface
