SHSG90 lightning protection standard resistor

SHSG90Lightning protection standard resistor | A. Lightning protection detection equipmentComposed of 9 1/2W high-precision military grade wire wound resistor series, it is easy to calibrate the instrument by directly shifting gears without changing wires, with a high precision of up to 0.05% and good long-term stability. It is a specially customized standard resistor for Shanghai Xuji Electric Co., Ltd. Its resistance values include 1m Ω, 10m Ω, 100m Ω, 1 Ω, 10 Ω, 100 Ω, 1K Ω, 10K Ω, and 100K Ω, within the range of 10-3-105 specified in the "Management Measures for Lightning Protection Device Testing Qualifications" (Order No. 31). Mainly used for calibration of grounding resistance testers, equipotential testers, and other instruments.

Order No. 31 of the China Meteorological Administration: "Management Measures for the Qualification of Lightning Protection Device Testing" has been reviewed and approved at the executive meeting of the China Meteorological Administration on April 1, 2016. It is now announced and will come into effect on October 1, 2016.

The "Management Measures for Qualification of Lightning Protection Device Testing" stipulate that the qualification level of lightning protection device testing is divided into two levels, A and B.

Qualified units can engage in the testing of lightning protection devices for Class, Class II, and Class III buildings (structures) as stipulated in the "Code for Design of Lightning Protection of Buildings".

Qualified units can engage in the testing of lightning protection devices for Class III buildings (structures) as stipulated in the "Code for Design of Lightning Protection of Buildings".SHSG90Lightning protection standard resistor
