Motwane’s new Digital clamp-on Earth resistance Tester, DECT-2 measures earth resistance using the clamp-on technology. Clamp-on is a relatively new method of determining the quality of a ground system. DECT-3 can measure earth resistance, earth bonds measurement & also measures AC leakage current. It’s actually recommended to use it on sites where there are multiple grounds placed in parallel and it is not required to isolate the ground rod. Simply clamp around the conductor or earthing strip and measure the earth resistance quickly and accurately. The unique big jaw is particularly suitable where grounding is done by flat steels or copper strips. It has a low battery indication & data hold facility with in-built memory storage of up to 99 test results. DECT-2 has a double insulation level and is protected from external magnetic & electric fields.

Features:

• LCD of up to 4 digits
• Range: 0.01 Ω to 1200 Ω
• Resistance measurement resolution 0.001 Ω
• Memory storage capability of up to 99 records
• Long jaw size: 65mm — 32mm φ
• The unique long jaw is particularly suitable where grounding is done by flat steel or copper strips
• Alarm setting feature with selection range available from 1 Ω to 199 Ω
• Double insulation level protected from the external magnetic field as well as electric field
• Automatic range selection, automatic self-calibration
• Single measuring time: 0.5 seconds
• Sound & Light annunciator: Beep sound, flashing symbol, ‘AL’ key to turn on-off & setting the sound & light alarm

Application:

The clamp-on measurement method is new and unique. It offers the ability to measure the earth’s resistance without disconnecting the ground. This type of measurement also offers the advantage of including the bonding to the ground and the overall grounding connection resistances along with indispensable troubleshooting tools to help you maintain uptime. It is recommended that all grounds and ground connections be checked periodically as a part of a normal predictive maintenance plan. If an increase in resistance of more than the acceptable limits is found during these periodic checks, then the engineer should investigate the source of the problem and make the correction to lower the resistance by replacing or adding ground rods to the ground system.

Typically Uses For:

• Measuring earth resistance of the electrical ground rod and grid. 
• Utility poles/Service entrance or meter
• Street lighting
• Lightning protection
• Street cabinets
• Telephone pedestals and telecommunication tower’s grounding
• Cell towers (applications with buried ground ring)
• Pad mounted transformer
• Pole mounted transformer
• Measures AC leakage current of transformer neutral
• Conduct field surveys quickly and effectively to retrieve and analyze the readings for later reference
