100KV Transformer Oil Breakdown Voltage Tester

Introduction

HJT series fully automatic transformer oil breakdown voltage tester is applied to test the insulating oil's dielectric strength, It widely used in many power systems, railway systems, large-scale petrochemical plants and enterprises,which have a lot of electrical equipment whose internal insulation are mostly oil-filled insulation type.It is designed as per the requirement of National standard GB / T507-2002, industry standard DL429.9-91 and the latest power industry standard DL / T846.7-2004, international standard  IEC 156, IEC 60296,ASTM D 1816,etc

This tester is via proper programming, getting functions of auto boosting, step down, stirring, display and print out.  After breakdown of oil medium, HV break off will operate within 10 seconds to enable an auto isolation of control system partly; this effectively safeguards the personnel security and equipment safety.

Main features

1. Simple operation, automatically (can be finished just press on key)
2. Menu controlled. Input data can clear
3. Can store 99 groups’ oil testing data which is convenient to reading and print. The testing data can keep 100 years under the condition of power off.
4. System time can go on running under power off; (The system time just for reference can not be the standard of timing)
5. Can upgrade software through RS232
6. High capacity of anti-jamming and high precision of testing.
7. Small volume, light which operated in the open air very conveniently.
8. The set shall be provided with smooth and continuous of output voltage between zero and maximum having no distortion of waveform.
9. Audio sound and visual signal will indicate at the instant of sample failure.
