Product Overview
XHEP701A Ground Grid Resistance Tester is a heterodyne high-current tester for large ground grid grounding resistance, applicable to substations (4Ω), thermal power plants, microwave stations (10Ω), lightning rods (10Ω) and other multi-purpose models.
Performance Features
This instrument integrates heterodyne AC power supply, microcomputer control and signal processing technologies, which resolves testing anti-interference issues, streamlines test operations, enhances test result accuracy, and cuts down test personnel's labor intensity and test costs substantially.
