Summary-table comparing the features.
The Amperis DryMAX® transformer dry-out system incorporates all the necessary features to allow a transformer to remain in-service while moisture from its insulation is effectively removed. The system is safe with several alarm features that shut the system off, isolating it from the transformer, in the event of any abnormal signal. The Amperis DryMAX5-1 unit provides a non-intrusive, cost effective and convenient method of maintaining transformers in a dry condition.
The TTRT 03B can store up to 200 test records in its Flash EEPROM. Each test record may contain up to 99 ratios, phase angle, excitation current, and all the plaque data of the machine. Test records can be saved and downloaded to a PC.
The TTRT 03A it is an accurate and automated triphasic transformation ratio meter. It operates with AC / DC power. It can work with a variety of voltages and various power sources, including 85 to 264 Vac, 110 to 370 Vdc, and 12 Vdc (car battery).
The Transformer turns ratio tester TTRT 03 it is a triphase transformation ratio meter which is lightweight, rugged and portable, designed to test transformers in electrical substations; it accurately measures the voltage in the transformer winding without load and then shows the voltage ratio (the ratio varies from 0.8 to 15,000).
The Transformer turns ratio tester TTRT 01 from Amperis is a second generation transformation ratio meter, based on a monophasic and automatic microprocessor. Determine the turns ratio of the transformer, accurately measuring the voltage in the winding of the transformer without load, thus indicating the stress relationship. It has A.C. power
Current transformer test AEZCT 2000 - It performs the current transformer saturation test (current transformer), measure the winding resistance of the Current Transformer and automatically transforms the turns ratio.
Current transformer test AEZCT 10 - Current transformers can be tested in their mounted configuration, thus eliminating the need to remove the bushings or current transformers of the central equipment.
Current transformer test AEZCT - This transformer tester, rugged and portable, measures the excitation current, transforms the ratio and polarity of the winding in single or multiple ratio current transformers.
Current transformer test AEZCT Serie 2 - Equipment for evaluation of Second generation microprocessor-controlled Current Transformers.
Dielectrotest is a fully automatic Dielectric strength meter for determining breakdown field strength of insulating liquid. It is designed for both laboratory and field use in commissioning and maintenance tasks.
The Myrkos is a dissolved gas meter in transformers which measures both the content of atmospheric gases (oxygen and nitrogen) and the seven fault dissolved gases. Designed for the laboratory, vehicle or field use, the Myrkos offers the fastest solution on the market for measuring dissolved transformer gases.
The TAND220A is a loss tangent meter in dielectric oil for control of the quality of mineral oil used as dielectric fluid in high voltage switchgear, such as power or measurement transformers, capacitors, terminals, etc. The instrument is based on the "square wave method of alternating current of low amplitude and low frequency" and allows accurate measurements of conductivity and relative permittivity.
