TRIORES-20 Series of instruments are designed to measure current transformers, voltage transformers and power transformer windings. Applying up to 20 Amps of direct current allows TRIORES-20 Series to measure the resistance of the transformer windings quickly and accurately. The TRIORES-20 instruments allow the operator to measure the resistance of both three-phase and single-phase transformer windings. It allows winding measurements to be performed without the need to disconnect and / or reconnect the cables from the transformer. Operators simply need to make the connection once to measure all three phases of a transformer. Starting at 0.1 uOhm, the TRIORES-20 series can measure up to 100,000 Ohm of resistance. It can control OLTC. The instrument tests resistance based on Intelligent Decision Criteria (IDC) where the device analyse the results for a period of time and if the measurement is stable under a specified value, the device decides to STOP the test and produce results. Manual operation is also available on TRIORES-20 where the operator can choose when to STOP the test depending on their preference. The TRIORES-20 series can demagnetise the transformer to mitigate the build up of remanence or residual magnetism due to the testing. The instrument also has a temperature measurement input which when connected to an optional temp sensor allows the TRIORES-20 series to perform temperature correction or adjustments to its measurements. In the case of a failure in the current circuit the TRIORES20s intelligent software controls the flow of current to mitigate damage and provide added safety for users. Device discharges through its voltage channels in case High Voltage is present in the transformer under test. Heat run test/Temperature Rise Test Heat run test or temperature rise test reproduces conditions of continuous rated load and the temperature rise occurring during the load. TRIORES-20 is capable of measuring the winding resistance of transformers and the full load resistance Ro during heat run test by applying up to 20A DC. A 7-inch colour touch display allows TRIORES-20 series to show all measurement results on a single screen. Field test results may be stored and recorded in the TRIORES-20s internal memory, (up to 100 Test Records) or many more on an external USB flash. Alternatively the operator may choose to employ the Data Management Platform (DMP Software) which allows PC based control of TRIORES-20 via a USB cable or the optional Bluetooth interface. This software platform allows the operators to analyze, edit and store measured results on a PC or laptop. If an immediate hard copy of the results is required the TRIORES-20 also allows for this via an embedded 2.28inch printer. An internal battery option is also offered for operators who feel that they may be in situations where a mains supply source isnt always available . Multilanguage capability and a user-friendly operating menu make it easy to control.
