Voltage tester DBF series

frequencyHipotfor electrical equipment

The DBF multi-frequency induction withstand voltage tester is designed for induction dielectric withstand tests on transformers and mutual inductors. It is portable, easy to operate and available in multiple power ratings for on-site electrical testing.

Key features

• Protection functions: overvoltage, overcurrent, zero-position start and flashover protection; overvoltage/overcurrent thresholds are user-settable and flashover protection activates to protect the test specimen.
• Lightweight and suitable for field use.
• Selectable automatic and manual operation modes to improve test throughput.
• Data storage and remote printing capabilities; tests stored with numeric identifiers for easy retrieval.
• DSP-based modular platform enabling function extensions and software upgrades; user-friendly HMI.

Maintenance and repair

• Before use: inspect unit for external damage, verify LCD display and outputs operate normally; clean corroded or aged output terminals before use.
• After each test: clean lead wires and terminals, power off and unplug; store in a dry, dust-free, ventilated location free of corrosive gases.

Transportation and storage

• For transport use the manufacturer's wooden crate with shock absorbers when possible to avoid damage; do not stack without proper wooden packaging.
• In original company instrument box maximum stacking is two layers; keep the control panel facing upwards during transport and storage.
• Store indoors in a dry, dust-free, ventilated, non-corrosive environment; place moisture-proof material under the unit to avoid dampness.
