Trusted by customers world-wide, T&R Test Equipment Ltd. is the UK's leading manufacturer of heavy current and high voltage electrical test equipment. Quality and reliability are ductor, low resistance measurement of relay test equipment, protective relay test paramount importance to us, and our ISO9001:1994 high current test equipment, primary injection approval reflects this. Our broad product range includes relay test equipment, primary current high voltage equipment, ac flash testers injection systems, test equipment manufacturers, high voltage test equipment micro-ohmmeters, DC cable test sets and AC flash testers. The unit has a range of outputs allowing injection of currents between a few mA and and 100A. Voltages- up to 240V are available on high voltage equipment, ac flash testers the main outputs, allowing high impedance current relays dc cable test sets, cable test equipment and voltage relays to be tested. Three true RMS metering ranges are provided, allowing the full scale of the meter and trip level to be set independently of the selected test equipment manufacturers, high voltage test equipment output. Industry cable testing systems, micro ohmmeters standard connectors are used on all inputs and outputs for convenience, reliability and safety. A three phase test, g59 testing range of optional dsm200, dsm600 auxiliary supply modules are available to complement the dc cable test sets, cable test equipment unit. These fit neatly into the case alongside the main high current test equipment, primary injection unit. Options cable testing systems, micro ohmmeters are available for fixed or variable relay test equipment, protective relay test auxiliary ac or dc supplies. Please ductor, low resistance measurement see the specification overleaf for details.
For example, testing a CDG11 disc induction dc cable test sets, cable test equipment over-current relay without a filter causes significant timing errors. The results below show the errors for a 1.3s 1A CDG11 over-current relay on its 0.5A test equipment manufacturers, high voltage test equipment plug setting, rocof relay testing, dvs3 tested at 5A. Three filter units are available: high voltage equipment, ac flash testers the 100ADM-F, the 100AFS, and the 100AFS-PH. All three ductor, low resistance measurement units have the same filtering characteristics and have current ranges covering 0.25A to 100A. The 100ADM-F is supplied three phase test, g59 testing in an relay test equipment, protective relay test insulated case to cable testing systems, micro ohmmeters match the 100ADM, complete with protective cover and carrying strap. The 100AFS has a steel case dsm200, dsm600 with carrying handles, but is otherwise high current test equipment, primary injection functionally test equipment manufacturers, high voltage test equipment similar and electrically identical to the 100ADM-F. The 100AFS-PH has all the features of the 100AFS, and also has a four position phase high voltage equipment, ac flash testers selector switch to simplify testing of three phase relays.
The CIT has a flexible timing system , allowing timing tests to be carried out to a resolution of 1ms. Selection for normally open or normally closed contacts is automatic, and the status of the dc cable test sets, cable test equipment contacts is test equipment manufacturers, high voltage test equipment shown on the front panel. Timing modes are available to test under dc cable test sets, cable test equipment and over current devices, re-closers, under and high current test equipment, primary injection over voltage ductor, low resistance measurement devices, and many current trips and circuit breakers. The CI differs from the CIT in that it does not have a timing system. The CI & CIT primary current injection systems three phase test, g59 testing are ideally suited to commissioning and maintenance high current test equipment, primary injection testing rocof relay testing, dvs3 where high currents up to 3000A are required. The ductor, low resistance measurement systems consists dsm200, dsm600 of separate control and loading relay test equipment, protective relay test units for maximum flexibility. The high voltage equipment, ac flash testers control unit cable testing systems, micro ohmmeters contains relay test equipment, protective relay test all control and metering circuitry, and is linked to the loading unit by control and metering cables. The units are capable of injection of currents up to 3000A with an LU3000LP loading test equipment manufacturers, high voltage test equipment unit.
