Brand: Megger

Whether you're testing circuit breaker contacts, switch contacts, busbar joints or simply measuring components for correct operation, the Megger DLRO200 is capable of carrying out comprehensive evaluation of low resistance levels.

The Megger DLRO200-115 measures contact resistance in high voltage circuit breakers, disconnecting switches (isolators), busbar joints, or for any other low resistance measurement. This test set accurately measures resistances ranging from 0.1 µΩ to 1 Ω, at high currents.

A versatile instrument, it can provide test currents from 10 A up to 200 A, subject to the load resistance and supply voltage. For those applications that demand a smooth DC current, the DLRO200-115 has extra filtering on the output to reduce mains frequency ripple and can drive 200 A through a total current loop resistance of 11 mΩ. The filtered output of the DLRO200-115 also eliminates magnetic transients that could inductively trip a breaker’s control (bus differential relay), if left in the test circuit.

Featuring three different measurement modes, the DLRO200 can be used to carry out continuous testing over a time period, conventional testing of single resistance levels and can carry out testing automatically with ramping current that adjusts as necessary to a conductor. Al tests are carried out using a four-terminal method, ensuring that the resistance of test leads is filtered out and the overall accuracy of a test is maintained.

As well as comprehensive measurement functions Megger's DLRO200 is also able to catalogue and interact with testing data. The tester allows storage of up to 300 individual test records on the device and it is possible to directly download this data into a PC or alternatively straight to a printer. An alpha-numeric keypad on the tester also allows the entry of notes associated with the stored information and allows adjustments to be made to values.

Properties:

  • Measure insulation resistance from 0.1μΩ up to 999.9mΩ
  • Test currents from 10 A to 200 A DC
  • 0.1 µΩ best resolution
  • On board memory for up to 300 test results and notes
  • RS232 port to download stored results or for real time output to a printer
  • Supplied complete with 5m test leads and download software
  • Small and weighs less than 15 kg

Key features:

  • LCD screen and alpha-numerical keypad
  • 300 record memory with download
  • 3 measurement modes: Continuous, Normal and Auto
  • High resolution and accuracy
  • RS232 communication
  • Autoranging digital meter for safety and ease of use
  • Safety rated to European Standard EN61010-1
  • Supplied with 5m lead set consisting of current and potential leads

The unique design allows the weight and size of the DLRO200-EN to be kept to a minimum; the instrument weighs less than 15 kilograms. This small size makes the DLRO200-EN equally suitable for applications in the workshop, on the production floor or in the field. The high current capability and compact design make the DLRO200-EN suitable for testing circuit breaker contacts, switch contacts, busbar joints or other applications where high current is needed.

300 sets of results may be stored in the DLRO200-EN's on-board memory for later download to a PC or may be output directly to a printer via the RS232 port. Users may also add notes to any stored result by using the on-board alphanumeric keypad, thereby making later identification of results straightforward.

As well as adding notes to stored results, the alphanumeric keypad allows you to set the test current directly by typing in the value required. The DLRO200-EN will check the continuity of the test circuit, and will quickly ramp the test current up to the desired level. The keyboard is also used to set upper and lower limits for the result and to prevent the use of excessive currents by setting an upper limit to the allowable test current.

The DLRO200-EN uses a four terminal measurement technique to cancel the resistance of the test leads from the measurement. It operates in one of three modes, which are simply selected from the on-screen menu.

About the manufacturer

Megger manufactures equipment for cable fault locating, protective relay testing, telecommunications and data integrity, and power quality testing under multiple brand names, among them Megger, Biddle, States, and AVO.

History of ‘Ducter’ testing
For over 100 years the ‘Ducter test’ has been used to describe a simple test for measuring very low contact resistances and “Ducter”, which is still used as a trade mark, was the name originally given to the low resistance ohmmeter manufactured by Megger. The name Ducter was registered by Megger in June 1908 and ‘Ducter’ has since become the industry standard.
