Descripción

Product description Product Introduction ETCR2000A Clamp Earth Resistance Tester, also known as clamp type earth resistance tester, earth resistance tester, loop resistance tester, single clamp earth resistance tester, which is used for measurement of earth resistance, loop resistance, and grounding fault judgment. In the loop grounding system measurement, no need to disconnect the grounding down lead, and not request the auxiliary grounding pole, which is safe, fast and convenient to use. The clamp earth resistance tester is widely used in earth resistance and loop resistance measurement of electric power, telecommunications, meteorology, oil fields, construction and industrial electrical equipment.The long clamp is particularly suitable for flat steel grounding site. The tester can measure ground faults that cannot be measured by traditional methods, and can apply to the site which cannot be measured by traditional methods, because the clamp earth resistance tester is measuring the comprehensive value of the grounding body resistance and the grounding lead resistance. Product Features Non-contact measurement is safe and fast. When measuring the loop grounding system, no need to disconnect the grounding down lead, and not request the auxiliary grounding pole, which is saving time and efficient.The clamp earth resistance tester can measure ground faults that cannot be measured by traditional methods, and can apply to the site which cannot be measured by traditional methods.With data hold function, memory function, alarm function. The ETCR2000A is designed for measuring loop resistance and is not suitable for single-point grounding tests. For single-point grounding measurements, please choose one of the following models from our store: ETCR3000, ETCR3040, ETCR3000B, ETCR3100C, or ETCR3200C. Specific Application Case Examples of an Earth Ground Resistance Tester Power Substations Verifies grounding resistance of transformers, switchgear, and transmission towers to ensure lightning and fault currents safely dissipate. Construction Sites Checks temporary grounding systems for cranes, generators, and site offices to comply with safety standards. Telecommunication Sites Measures ground resistance of telecom towers and base stations for reliable signal transmission and lightning protection. Commercial & Multi-Grounded Systems Measures ground loop resistance in systems with multiple parallel grounding paths, such as commercial buildings, facilities with interconnected grounding networks, and industrial installations. Not intended for single-point or typical residential ground rod testing.

Características

• Wide Application: Ideal for measuring grounding resistance in power, meteorology, oilfields, construction, and industrial electrical equipment. No need to break down grounding leads or use auxiliary electrodes for loop system measurements
• Advanced Functionality: Measures ground faults undetectable by traditional methods, making it suitable for applications where conventional meters fail. Accurately measures the combined resistance of the grounding body and lead
• Measurement Range: Offers a wide measuring range from 0.010Ω to 500Ω with a high resolution of 0.001Ω. The clamp jaw size is 55X32mm, opening size is 32mm, ensuring versatility in various testing scenarios
• Precision Measurement: Utilizes loop resistance measurement, combining voltage and current coils. It measures induced potential and current to calculate resistance using the formula R=E/I for precise results
• Important Notice: Designed to measure loop resistance only, not single-point grounding. Users can create an artificial loop near the grounding electrode for testing. Refer to the user manual for detailed instructions
