GOZ-DW-3A Substation ground resistance tester
The newest industry standard DL/T475-2006 and national standard GB/T17949.1-2000 were worked out because the testing work of grounded equipments is weak , and some pivotal technique conceptions are obscure. According these standards and our practical experience for Geodetic Network , this new equipment was developed.
