The 5250 primary cable fault locating system meets the demanding needs of electric utilities, electrical contractors, or any company testing medium to high voltage cables that require a highly portable, easy-to-use thumper system for quickly restoring electric service.
The 5250 utilizes an innovative, time domain reflectometer (TDR) along with the highest energy, battery-operated thumper on the market. The 5250 will reduce cable fault locating time by up to 80%. The 5250 can test faulted, loop feed underground residential distribution (URD) cable systems without having to disconnect transformers in an effort to sectionalize the cable fault between two transformers.
The battery powered 5250 combines a capacitive discharge, high voltage filter, digital TDR, and battery charger into one complete package. The operator can control all test functions through the digital TDR or by using the analog, high voltage controls on the 5250 front panel. The 5250 is connected to the cable under test using quick clamps and MC adaptors. Once the 5250 primary cable fault locator is connected to the cable under test, a trained operator can find faults in a matter of minutes.
The 2293 is an automatic winding analyzer, optimized for three phase power and distribution transformer
It uniquely combines winding resistance measurement, turns ratio measurement, core demagnetization, transformer type detection, magnetic balance and heat run test (temperature rise and cooling curve) in the fastest single instrument solution on the market.
The 4761 high precision standard current comparators is used as comparison standard in the differential method (bridge) measurement of current instrument transformers together with the measuring instruments type 2763 and 2767. The special active flux compensated design of these comparators results in negligible current errors.
These units can also be used as current measuring range extension for C and tand measuring equipment.
The 3692 is an additional burden extension that provides a power range that is expandable up to 200VA.
This programmable current burden unit is ideal for integration with the 2767 or 2763 test set in a full remote controlled instrument current transformer test system.
The MIDAS micro 2883 is a revolutionary C Tan Delta / Power Factor / Dissipation Factor tester used to test the insulation of high voltage components (i.e. transformers, bushings, capacitors and so on). Designed and tested for all types of conditions, the complete instrument is built in one rugged case with casters.
With its single-box design, weighing only 25 kg / 55 lbs, this tool can be easily transported to any testing location – in the field or in the factory. All accessories are stored in a robust duffel bag that can be affixed to the case itself. Cable drums make set-up and storage quick and convenient.
MIDAS stands for Mobile Insulation Diagnosis Analyzing System.
