Accessories
The typical accessories for this tester include:
(1)Oil Heating Tank / Bath – Heats the insulating oil to the required high temperature.
(2)High Voltage Electrodes – Usually plate-to-plate or sphere-to-sphere configuration for dielectric testing.
(3)Temperature Controller – Digital or analog controller to regulate oil temperature precisely.
(4)High Voltage Generator – Provides controlled AC or DC voltage for dielectric breakdown testing.
(5)Safety Guard / Cover – Transparent shield to prevent oil splash or accidental contact with high voltage.
(6)Thermometer / Thermocouple – Measures oil temperature accurately.
(7)Test Sample Holder / Cell – Holds insulating oil and positions electrodes properly.
(8)Voltage & Current Meters – Monitors applied voltage and leakage current during testing.
(9)Alarm System / Emergency Stop – Ensures operator safety in case of overvoltage or equipment failure.
(10)Calibration Accessories – Standard gap spacers, reference oils for calibration verification.
