SCR ELEKTRONIKS
SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.

Premier Electrosystems
The Earth Contact Resistance Tester is a basic safety test prescribed in many IS standards. The goal is to test samples for the proper connection of earthing wire with the appliance. Premier's ECR tester checks the contact resistance between accessible metal parts of the appliance and the Earth pin by passing a high current and measuring the resultant voltage drop.

Standard Electric Works Co., Ltd
● Microprocessor-controlled.● Measures Earth Resistance without the need for poles in the ground or external measuring wires.● Earth measurement uses the real earth current path and the current generated by the electric network, without the need for any disconnection.● The Earth Resistance displayed is exactly the earth resistance that the earth current will need to go through if an earth fault occurs. (you do not need to add all the bonding points and connection paths)● Displays voltage supply at the transformer(Line to Neutral), without loading the transformer.● Single one smart push button operation; ON, Scroll through results and menus.● Checks wiring integrity (LEDs).● Auto-off / Auto-ranging (software range).● Color-coded test leads.● Combined prospective short circuit current, loop, and earth tester.● Loop test for L-E and PSC between L-N.● Voltage test L-N.● Display can be customized for large orders.

Shenzhen Chuangxin Instruments Co., Ltd.
Ground Earth Resistance Tester verifies the integrity (continuity) of the protective bonding of the equipment (Class I equipment) designed to secure safety through the basic insulation and protective earthing. It is also called earth (ground) bonding test. If the continuity of the protective bonding is confirmed, we can conclude that the equipment has the requirements for preventing electric shock even if the insulation between the primary circuit and the accessible conductive section fails and a fault current flows through the distribution system.
