HDE QC-AST-N Transformer and Capacitor Tester

Overview

The HDE QC-AST-N is a quick-check transformer and capacitor tester designed for field and shop use. It provides single push-button operation for rapid verification of open circuits, short circuits, and healthy equipment status. The automatic self-test feature ensures reliable operation by verifying battery, lights, beeper, and all electronics with each test cycle.

Key Features

• Single push-button operation for quick testing
• Automatic self-test of battery, lights, beeper, and electronics
• Tests transformers for primary and secondary shorts or opens, including internal fuses and breakers
• Tests capacitors and capacitor banks individually or in arrays
• Clear indications of open circuits, short circuits, and OK status
• Tests de-energized equipment without disconnecting primary and secondary sides
• Automatic distinction between transformer and capacitor measurements

Applications

• Field testing of overhead and pad-mount distribution transformers before energizing
• Incoming and outgoing transformer screening in manufacturing and shop environments
• Single-phase (1Ø) and three-phase (3Ø) transformer testing
• Testing potential and instrument transformers
• Capacitor and capacitor bank testing before installation
• Verification of secondary connections on transformer installations
