GDHL The Line Loop Resistance Test /HV meter/ line loop resistance meter
GDHL-III type the line loop resistance test instrument adopted digital
circuit technique and the switches circuit technique creation, is used for the
switch control equipments of the contact resistance, the line loop resistance
measure of appropriation equipments. the measurementcurrent adopts the national
standard GB763 recommend of the 100 A direct current, can measure directly under
the circumstance of the 100 A current the line loop resistance perhaps contact
resistance, and direct manifestation, that instrument measure accurate,
functionstability, the spot high voltage switch maintains with the request of
the line loop resistance test in the high voltage switch factory in the in
keeping with electric power, the power supply
