Portable High Precision Ground Grid Resistance Tester
|
Detailed Product Description
Product OverviewXHEP701A 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 FeaturesThis 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.
