This paper presents the results of experiment basea evaluation method for technical characteristics of metal oxides varistors zinc (V-MOV-ZnO) which makes up 110 kV surge arrester. All tests were implemented at the National Key Laboratory for High Voltage Techniques - Institute of Energy (HVLAB). The 8/20 uS standard lightning impluse current tests were performed to test for the residual voltage; the voltage-current characteristics of metal oxides varistor zinc V-MOV-ZnO. Moreover, the voltage-current characteristics of V-MOV-ZnO was tested with 1mA current passed through resistor plate of V-MOV-ZnO. Once voltage applying to the V-MOV-ZnO is greater than Upeak, a small increasement of voltage will result in a very high current passing through the V-MOV-ZnO. This feature is used to discharge the lightning when very high transient over-voltage occurs. Upeak is reffered as a limit which must be taken into account when designing the V-MOV-ZnO arrester. All testing results practically allow to evaluate quality of the VMOV-ZnO on some aspects arrcording to lEG 60099-4 and to ensure the effectiveness of surge arrester if utilized.
