The device is designed to test insulation voltage between two conductors and to verify insulation integrity in electrical components. Key capabilities - Tests insulation voltage between two legs of an object such as switches, buttons, and connectors. - Facilitates insulation testing between windings in electrical equipment, including motors, industrial-frequency transformers, and high-frequency transformers. - Supports phase-to-phase insulation testing and insulation measurement of shell/core structures. Use scenarios - Electrical panel maintenance: quickly verify insulation between two legs of switches, buttons, or connectors to identify leakage paths or degraded insulation. - Motor servicing: check insulation between windings in motors to ensure safe operation and prevent winding faults. - Transformer inspection: perform insulation tests between windings in industrial-frequency or high-frequency transformers, including phase-to-phase and shell/core insulation verification. Notes - Follow applicable safety procedures and testing guidelines when performing insulation voltage tests.
