HZM9010 Lightning Protection Standard Resistor

Name: China HZM9010 Lightning Protection Standard Resistor Manufacturers Suppliers Factory - Huazheng Technology
Brand: Huazheng
SKU: 255641056

Huazheng HZM9010 Lightning Protection Standard Resistor is a resistance device used to test lightning protection equipment. Its primary function is to simulate the scenario when lightning strikes buildings or equipment, directing the current into the ground through the grounding system to protect the structures from damage. These resistors are typically made from high-purity copper or aluminum, offering low resistance values and high durability. The resistance value usually ranges from several hundred ohms to several thousand ohms, depending on the design and specifications of the grounding system.

HZM9010 Lightning Protection Standard Resistor

Products Description

I. Brief Introduction

The HZM9010 Lightning Protection Special Standard Resistor consists of nine 1/2W high-precision, military-grade, wire-wound resistors. During calibration, there is no need to change the connections, allowing for direct switching. The test process is convenient, with a maximum precision of up to 0.05% and excellent long-term stability. This special standard resistor is specifically designed by our company.

Its resistance values include 1mΩ, 10mΩ, 100mΩ, 1Ω, 10Ω, 100Ω, 1KΩ, 10KΩ, and 100KΩ, covering the full range of 10⁻³ to 10⁵ as specified in Order No. 31 of the Measures for the Administration of Detecting Qualifications of Lightning Protection Devices. It is primarily used for the calibration of grounding resistance testers, equipotential testers, and similar instruments.

II.Application scenarios and importance

Lightning Protection Standard Resistors are primarily used to test the grounding systems of lightning protection equipment. When lightning strikes buildings or equipment, the lightning protection standard resistor simulates the lightning current, allowing the measurement of the resistance value and effectiveness of the grounding system. This ensures the grounding system's reliability and efficiency.

By measuring the grounding resistance, the performance of the system can be evaluated to ensure its ability to quickly direct current into the ground during lightning strikes, thereby protecting both equipment and personnel.
