SCOPE introduces state of the art precision three phase Transformer Turns Ratio Meter (TTRM ) designed for field testing as well as factory testing of power transformers, instrument transformers and distribution transformers of all types. Along with turns ratio, this light weight and reliable instrument measures ratio deviation, phase angle deviation, magnetizing current and detects tap-position of single as well as three phase transformers in charged switchyard condition. The instrument has facility to automatically detect vector group of all majority configurations available. The differant AC voltage selection offers high accuracy in measurement.

Instrument has in-built TFT display with touch screen and thermal printer. The user friendly, simple instrument makes the testing more easy. With the touch keypad it is possible to enter required DUT information. The ratio results of all the phases are displayed in tabular form with % error. Internal non volatile memory gives the provision of storing test results. Further data can be downloaded to PC or copied to memory stick through USB port provided. The CTrans-TTRM software, gives the flexibility to download the stored results to PC and do the further analysis and report generation.

TRM104 is a portable winding resistance meter, designed to work in live EHV switchyards. Winding resistance values of large transformers up to 500 MVA and rotating machines are directly displayed. The meter is protected against the back emf offered by large inductive winding. A back-lit 4 line LCD with a user-friendly menu sets up the instrument for the test. Winding resistances and safety messages are also shown on this display. It is possible to measure the resistance of two windings simultaneously.The meter contains a special power source for rapid stabilization of test results.

A 30V DC, 10 Amp power source, controlled strategically by digital means passes the selected current through the winding. Precision instrumentation amplifiers read voltage developed across the windings and the ohmic values are directly displayed. Use of the classical Kelvin’s 4-wire method ensures reliable measurement. Specially designed thermal management of power source enables measurement over longer periods, when delta connected generator transformers are tested. The TRM is capable of identifying the interruption of injected current during tap change of OLTC. A beeper alarm during current injection ensures operator safety during measurement.

SCOPE proudly introduces Dir CT, a CT Polarity Tester specially designed to verify correctness of polarity of current transformers cores in live EHV switchyards. Polarity test is one of the most common yet crucial tests required to be done on current transformers by commissioning as well as maintenance engineers. Even though it is commonly conducted check, there was no all in one simple tool available for this measurement. DIR CT fills this void to perfection, it is expected to significantly reduce the time taken for polarity checks on numerous CT in sub-station, especially during commissioning of new sub-stations

It is must have tool for Testing & Commissioning companies.

CRM 100B directly measures micro-ohm values at 100 Amps DC under live switchyard conditions.

CRM 100B is specially designed to reliably measure contact resistance of circuit breakers, isolators, busbar joints, welded joints etc., under the hostile electrostatic noise found in live EHV switchyards upto 765 kV.

Inbuilt rechargeable battery tremendously enhances utility as AC supply connectivity is not required.

CRM 100B operates on a rechargeable battery as well as Mains supply. It has a built-in constant current source, a precision instrumentation amplifi er, digital readout and control logic.A pulse of 100A DC is passed through the test object and voltage drop is sensed using the classical Kelvin’s 4 wire method to measure contact resistance. Both test current and resistance value are displayed on LCD.

CRM 100C directly measures resistance values with DC current injection under live switchyard conditions.The CRM 100C is specially designed to reliably measure contact resistance of Circuit Breakers, Isolators, Bus Bar joints, welded joints etc., under the hostile electrostatic noise found in live EHV switchyards. It can also be used for testing cables, graphite bars etc.

It has a truly continuous current source without any ON/OFF duty cycle
