Turns Ratio Testers
TRT Standard Series
-
When it comes to choosing a transformer turns ratio tester, TRT Standard series offers some of the most advanced instruments with LCD display out in the market. Each model measures transformer excitation current and phase shift performs automatic vector group detection and magnetic balance on three-phase transformers and three-phase autotransformers. Furthermore, they have a built-in true three-phase power source. Because of that, TRT Standard instruments can test transformers with special configurations, such as phase-shifting, rectifier, arc-furnace, traction transformers, etc.The instruments can output test voltages from 1 V AC to 250 V AC, depending on the chosen model. High test voltage of 250 V AC provides more accurate turns ratio testing compared to other turns ratio testers on the market and extremely low test voltage of 1 V AC enables turns ratio verification of current transformers.TRT Standard series consists of:TRT03 Models (TRT03A, TRT03B, TRT03C) – single-phase voltage up to 100 VTRT3x Models (TRT30A, TRT30B, TRT30C, TRT33A, TRT33B, TRT33C) – single and true three-phase voltage up to 100 VTRT63 Models (TRT63A, TRT63B, TRT63C) – single and true three-phase voltage up to 250 VMore about models differences can be found under the downloads tab, in brochures and comparison sheets.A user can create test templates using the DV Win software and store them in the PC’s memory for later use when in the field.TRT Standard series models have a built-in tap changer control unit. Consequently, it enables remote control of an on-load tap changer (OLTC) directly from the tester. In order to make the most out of this feature, the DV-Win software can be programmed to do everything automatically – running turns ratio tests, changing OLTC tap positions and saving results. This option, especially in combination with test templates, significantly facilitates and shortens the turns ratio testing time.

Gauss Meters
-
A gauss meter displays electromagnetic wave measurements in Gauss (G), milliGauss (mG), milliTesla (mT) or microTesla (µT) units. A gauss meter can detect either static (DC) permanent (rare-earth) magnetic or dynamic (AC) electromagnetic fields (EMFs), or both. Thus, it is important to review the specifications of a gauss meter prior to purchase to ensure suitability for the intended application.Neodymium (NdFeB) permanent magnets are among the world's strongest and most widely used magnets. When testing magnets made of neodymium or other rare-earth elements, a gaussmeter or magnetometer capable of measuring DC magnetic fields is required. However, most electromagnetic fields encountered are generated by AC currents. Examples include electrical power lines, transformers and wiring for overhead lighting, solar panels and other electrical devices and equipment. Electromagnetic fields from electrical installations are believed to cause feelings of nervousness, anxiety and paranoia in EMF-sensitive human beings.Most gaussmeters offered by PCE Instruments can be calibrated and certified according to DIN ISO 9000 standards for an additional fee. Replacement gaussmeter probes and optional accessories are available for most gaussmeter models.
