Special DevelopmentsConstant current test set UIVPT-200This special device is intended for testing insulators following requirements IEC 601325 (1995) with standart (GOST 1516.2) normative constant voltages up to 200 kV. Device provides measurement of values of test voltage in processe of the tests according to requirements of measurement systems for high voltages GOST 17512 (IEC 60060-2). Technical parameters of this device is accessible up to this link . This device represents placed on a non-standard frame: transformer IOG-100/7,5 , rectifier and voltage divider DN-200EO . For convenience of movement the frame is equipped with wheels. Couple of rotary wheels are supplied with a stopper. Constant current test set UIVPT-200
HVS-500 direct voltage standard source is designed for appliance as part of the calibrating instrument for periodical potential transformers calibrations on-site.HVS-500 generates controllable d.c. voltage (20...500) kV with high accuracy and stability (± 100 V, I = 30 mA). HVS-500 direct voltage standard source
DN-220pt voltage dividerDN-220pt voltage divider is designed for class 35, 110 and 220 kV potential transformers on-site calibration.
The divider has three standard division coefficients, small overall dimensions and weight, transportation tolerance. Divider specifications are shown in table:
* — Value for sealing off Standard calibration certificate, issued by FSUE "D.I.Mendeleev VNIIM", is accompanied with the divider. |
