Data Sheet

Automatic Insulating Oil Tester DPA 75 The portable insulating oil tester DPA 75 measures the electric breakdown strength of insulating liquids.

Features: • functional and ergonomic design

• test voltages from 0 up to 75 kVrms

• multiple breakdown measurements on silicone oil samples are possible due to short breakdown time (< 1 ms) and current limiting

• built-in sensor for acquisition of temperature of the insulating liquid

• integrated plain paper printer for automatic reporting of test data (option)

• interlock (forced-contact) switch for protective hood

• an oil-proof touch panel and an easily readable graphics display enable optimal and comfortable user communication

• compact design, low transport weight as well as a shoulder strap and a carrying handle (option) for easiest portability

• mains and battery operation Test vessel • Exact setting of electrode spacing by means of a built-in vernier and an electro-acoustic zero spacing

control • menu programme for electrode cleaning breakdown

DIELTEST DPA 75

SELF TEST 10

The ergonomic design of the DPA - compact, functional and user-friendly! 1 Gripping strip for opening/closing the protective hood. 2 Protective hood with self-acting mechanical locking mechanism (interlock switch - forced contact). For

highest operational safety! 3 Test vessel with electrodes - available for all national and international standards. Quickly removable

test vessel for easy cleaning! (ref. to selection table of page 6! ). 4 Solvent-proof oil pan. 5 Carrying handle and shoulder strap - for easy and simple mobile use option. 6 Built-in rechargeable battery - for mains independent operation. Integrated power supply for controlled

battery charging (option). 7 Bi-directional RS 232 interface - for calibration by a PC. 8 Folding front panel - switches the DPA on/off automatically. 9 Built-in plain paper printer - for automatic reporting of test data (option).
