10 Amp Current Transformer Burden Test Set (1043)
Quickly diagnose CT installation issues without interrupting service. TESCO’s 10 Amp Current Transformer Burden Test Set is a compact and affordable tool for quickly identifying CT installation issues, while the meter remains energized and the customer stays in service.
Key Features
- Four selectable current ranges: 1.25, 2.5, 5, and 10 amps
- Six built-in ohmic burden values: 0.1, 0.2, 0.5, 1.0, 2.0, and 4.0 ohms
- Half-scale to full-scale range continuity for optimal readability
- Large, easy-to-read 2.5” panel meter with unbreakable plastic cover
- Push-button burden insertion for in-line testing
- Molded, non-conductive black plastic case with white panel markings
- Designed with built-in safety to prevent accidental CT secondary opening
Description
Designed with utility safety and accuracy in mind, the test set ensures that the CT secondary circuit remains continuously closed, even when switching settings or inserting burden. The unit functions as a multi-range ammeter with selectable internal burden values, making it ideal for testing under live load conditions.
Applications
Use the 1043 to detect and diagnose:
- Shorted CT primary or secondary turns
- High resistance joints or bad CT connections
- Grounding issues or unintentional grounds in ungrounded systems
- Tampering or abnormal wiring conditions
- General CT installation errors
