Resistance measuring instrument TRIORES-20

currentindustrialtransformer

RIORES-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 μΩ, the TRIORES-20 series can measure up to 100,000 Ω 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 TRIORES20's intelligent software controls the flow of current to mitigate damage and provide added safety for users.
