Hilkar
Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.

The Motwane Manufacturing Company
Motwane is India’s first company to design and develop an intelligent digital insulation tester that conducts insulation resistance tests on high voltage electrical equipment. Products like transformers, generators, motor cables, bushings, LAs, and switchgear, are prone to gradual degradation over time due to the adverse effects of temperature, humidity, and dust. The gathered test data allows clients to verify the current quality of insulation, and take appropriate action.

Standard Electric Works Co., Ltd
● Microprocessor-controlled.● Measures Earth Resistance without the need for poles in the ground or external measuring wires.● Earth measurement uses the real earth current path and the current generated by the electric network, without the need for any disconnection.● The Earth Resistance displayed is exactly the earth resistance that the earth current will need to go through if an earth fault occurs. (you do not need to add all the bonding points and connection paths)● Displays voltage supply at the transformer(Line to Neutral), without loading the transformer.● Single one smart push button operation; ON, Scroll through results and menus.● Checks wiring integrity (LEDs).● Auto-off / Auto-ranging (software range).● Color-coded test leads.● Combined prospective short circuit current, loop, and earth tester.● Loop test for L-E and PSC between L-N.● Voltage test L-N.● Display can be customized for large orders.

TWA Standard Series -
IBEKO Power AB
When it comes to winding resistance measurement on three-phase power transformers and autotransformers, TWA Standard series offers some of the most technically advanced instruments with LCD display in the market. Both models are capable of testing six transformer windings with a one-time cable connection, as well as three-phase automatic transformer demagnetization. The stored magnetic energy is safely automatically discharged at the end of the test. The built-in tap changer control unit enables automated test mode, where the instrument operates the tap changer without operator input and records winding resistance results based on pre-selected stabilization criteria. This option makes the operator’s job significantly easier.Both models can output test currents from 5 mA to 25 A DC for the purpose of winding resistance measurement. TWA40D has a special test mode for checking the synchronization of on-load tap changers with three phases simultaneously tested in parallel, in which the total test current can rise to up to 40 A DC.TWA40D has additional advantages when it comes to non-intrusive tap changer analysis. The unique DVtest method enables checking the moving contacts of on-load tap changers during the transition, measuring the transition time, detecting open circuits, and many other types of faults. It is performed with 0.1 ms sampling rate, simultaneously with the measurement of tap changer motor current which helps with the detection of motor and mechanical issues. A special proprietary algorithm is used for testing tap changers connected through a built-in series (booster) transformer. The DVtest can be performed either on one phase or on three phases simultaneously. It can also be performed as an additional test simultaneously with the winding resistance test in all tap positions.An additional unique advantage of TWA40D is the capability of simultaneously testing the winding resistance of all three phases of a three-phase transformer (connected in a YN configuration). This can significantly shorten the total testing time – for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.The test leads for TWA three-phase transformer winding ohmmeters are interchangeable with the TRT turns ratio testers, which means that both sets of tests can be performed with a single test lead connection to the power transformer terminals.
