Dielectric Loss Tester
Darui Electric recommends：
Dielectric Loss TesterNovel intelligent instrument for measuring tgδ and Cx. 。Field measurement under HV for insulating materials, bushings, cables, capacitors, CT/PT, transformer and other HV equipment D/L tangent(tgδ) and CapacitanceCx.
Product Features
Simple wiring (2 wires normal, 1 reverse), all cables shielded, ground-drag usable. Auto ramp, direct reading, no conversion.
Multiple modes: normal/reverse wiring, int/ext std cap, int/ext test voltage.
HV D/L measurement capable
Anti-vibration: withstands strong vibration during transport.
Strong anti-interference: auto tracking compensation, vector+phase shift, eliminates E-field interference for 500kV substation tests.
TBD
Safety: (1) HV protection: rapid cut-off on short, breakdown or current fluctuation.
(2) CVT protection: auto exit on overcurrent setpoint, no damage.
(3) Ground detection: cannot boost without proper grounding.
(4) Anti-misoperation: detects common wiring errors, safety alarm.
(5) Anti-capacitive rise: auto tracks output voltage, maintains constant test voltage for large-capacity test objects.
VFD display: large dot-matrix, clear in all seasons. Full Chinese
Chinese menu with warnings, intuitive, no manual needed.
Print: built-in micro printer for Chinese results and status.
RS232 for PC connection for data processing and saving.
Optional PC communication software available.
