High voltage direct current（HVDC） voltage transformers for DC transmission projects in China have been imported for a long time. With the rapid development of DC transmission and distribution technology

the HVDC voltage transformers will be more and more demanded

thus it is of great significance to realize the autonomy of HVDC voltage transformer. The precision resistors

as the key components of HVDC voltage transformers

will determine the degree of autonomy of HVDC voltage transformers. Consequently

we investigated the precision resistors made in China

and reviewed the research-and-development status of precision resistors. The results show that the performances of precision metal film resistor and precision thick film resistor made in China can meet the design requirements of 0.2 class HVDC voltage transformer

whereas the resistance target materials and resistance paste mainly rely on importation. Compared with imported resistors

the precision metal film resistors made in China have the smaller limiting voltages and larger temperature coefficients at the same resistance values. Compared with imported resistors

the precision thick film resistors have the smaller temperature coefficients and lower limiting voltages. To realize the autonomy of precision resistors in China

we can explore the methods to increase the target resistivity and reduce the inductance of precision metal film resistor. For the precision thick film resistor

we can explore better particle size distribution of the resistor paste and the methods of reducing temperature rising.
