I.Application :


This test set model CHX-9000KVA/150KV,300KV,450KV is designed for 132kV~400KV class long XLPE cable on-site AC hpot test and 362KV and below class GIS on-site AC hipot test with variable frequency resonant circuit technology; the highest test voltage is no more than 150KV,300KV,450KV through cylinder test reactor in parallel or in series connection ;the test frequency can be from 20-300Hz; the duty cycle is no more than 60mints.


Through modular test reactor is used in parallel or in seires, the test set model CHX-9000KVA/150KV,300KV,450KV also can be performed the following on-site AC hipot test:

1.1 No more than 150KV and 60A for long distance XLPE cable with no more than U0=87KV

1.2 No more than 300KV and 40A for long distance XLPE cable with no more than U0=160KV ;

170KV and below class GIS

1.3 No more than 450KV and 20A for long distance XLPE cable with no more than U0=230KV ;

362KV and below class GIS


Until now , these designed test set can form many different serialized model according to different HV or UHV withstand test applications through test reactors in series or in parallel connection and number of configurations in each set, The alike model can see clause 9.other typical model.
