DESCRIPTION

The DLRO-H200 is designed to measure the resistance of

circuit breaker contacts, bus-bar joints and other high-current

links. This product is designed with safety, ease of use and

versatility in mind.

This Micro-ohmmeter can be used anywhere to measure a

low resistance value with high accuracy.

With DLRO-H200, it is possible to make measurements

according to the DualGround

method. This means that the

test object will be grounded on both sides throughout the test

giving a safer, faster and easier workflow.

Rugged and lightweight, the handheld DLRO-H200 is very

suitable for field work, in substations and similar locations.

The unit comes with a strong rubber holster that makes it

extra durable. The DLRO-H200 is designed to carry out a full

day of testing without recharge. It can store 190 test values

and transfer test data to a PC via Bluetooth.

The Bluetooth feature can also be used in conjunction with

the wireless headset (supplied) to provide an audible pass/

fail signal against user adjustable limits as tests are performed.

DLRO-H200 micro-ohmmeters are supplied with a copy of

the PowerDB Lite software package. This intuitive software

offers powerful features for storing, analyzing and archiving

test results, and it supports reporting a wide range of industry

standard formats. It also makes it easy to integrate results

from the DLRO-H200 with results from other instruments to

produce uniform reports.

APPLICATIONS

The DLRO-H200 test system is designed to serve a number

of applications. The most common are contact resistance

measurements of low-, medium- and high-voltage breakers

and also at bus-bar joints and other high current links.

If the contact resistance is too high this will lead to power

loss and temperature rise, which often leads to serious

trouble. To avoid such problems, it is necessary to check the

resistance at regular intervals.

The following table demonstrates how important low

resistance is at high currents:

Current Contact resistance Power loss

10 kA 1 mΩ 100 kW

10 kA 0.1 mΩ 10 kW

1 kA 1 mΩ 1 kW

1 kA 0.1 mΩ 100 W

At 10 kA, a contact with the resistance 0.1 mΩ gives a

power loss of 10 kW. This power loss in one single point

will definitely confer a temperature rise, which may result in

overheating and possibly premature failure.
