WINRES-20 has been designed to measure the resistance of current, voltage and power transformer windings as well as shunt resistors. It is able to apply up to 20 Amps of direct current allowing the instrument to measure the resistance of a transformer winding quickly and accurately.
The instrument also has two measurement channels allowing simultaneous resistance measurement of two windings in any configuration such as, two primary or two secondary or one primary and one secondary winding, the choice will depend on the configuration of transformer/s.
Starting from 0.1 uOhm, the WINRES-20 instrument series can measure up to 100,000 Ohm of resistance. To avoid residual core magnetisation or remanence of a transformer the WINRES-20 series of instruments will de-magnetise the transformer after each test. The instrument also has a separate temperature sense input which allows the operator to automatically correct for temperature variation. An optional sensor is available for this input. 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. As a result, the operator doesnt need to inspect the measurement values continuously on the display or stop the test manually (manual operation is also available). In the case of a failure in the current circuit, the WINRES-20s 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. WINRES-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 WINRES-20 to show all measurement results on a single screen. Field test results may be stored and recorded in the WINRES-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 WINRES-20 via a USB cable or the optional Bluetooth interface. This software platform allows the operators to analyse, edit and store measured results on a PC or laptop. If an immediate hard copy of the results is required the WINRES-20 also allows for this via an embedded 2.28-inch 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.
With its single-phase cable configuration, users can measure winding resistance of single-phase transformers as well as three-phase transformers. For three-phase transformers, each phase needed to be measured separately as WINRES has a single-phase cable configuration.
