3 FRAX-150 Sweep Frequency Response Analyzer

Power transformers are some of the most vital components in today’s transmission and distribution infrastructure. Transformer failures cost enormous amounts of money in unexpected outages and unscheduled maintenance. It is important to avoid these failures and make testing and diagnostics reliable and efficient.

The FRAX 150 Sweep Frequency Response Analyser (SFRA) detects potential mechanical and electrical problems that other methods are unable to detect. Major utilities and service companies have used the FRA method for more than a decade. The measurement is easy to perform and will capture a unique “fingerprint” of the transformer. The measurement is compared to a reference “fingerprint” and gives a direct answer if the mechanical parts of the transformer are unchanged or not. Deviations indicate geometrical and/or electrical changes within the transformer.

4 MTO-330 Transformer Ohmmeter Test Set

The MTO series delivers full eight-terminal/six-winding resistance measurement capability. It is designed to save time by testing all six windings without having to disconnect and reconnect leads. Also, the simultaneous winding magnetization (SWM) method gives fast and reliable measurements even on large transformers with delta configuration on the low voltage side.

Additionally, the MTO series leads are interchangeable with the Megger TTR series of three-phase turns ratio instruments which eliminates additional connecting time for turns ratio measurements. The MTO330 offers the same functionality as the MTO300. However, it is equipped with an onboard computer featuring full QWERTY keyboard and navigational pushbuttons as displayed on an 8.4 inch full-color VGA transflective screen viewable in bright sunlight.

5 TTR-330

The TTR300 Series of three-phase transformer turns ratio test sets are designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment. A rugged and robust design makes these instruments well suited for use in a variety of harsh environments. Our leads are specially designed to provide the necessary flexibility needed in cold weather.

The TTR300 Series are ideal for use by power transformer manufacturers. Their unique testing procedures and storage capability allows an operator to set up and test difficult three-phase transformers (with multiple tap changers and bushing CTs) in a fraction of the time than it used to take with other TTRs. This test also includes a pass/fail limit of individual ratios. The TTR300 Series also measure the phase deviation of the transformer primary versus secondary. This quickly indicates problems in the transformer such as partial shorted turns and core faults. This measurement is also useful in verifying phase errors in all types of PTs and CTs.

6 Insulation Resistance Tester – MIT-1025

The new insulation resistance tester MIT1025 is available up 20 TΩ for the 10 kV model. The new instrument is smaller and lighter than previous models yet offer advanced features and rapid charge capability. A key productivity feature is the ability to take measurements when connected to line power/mains with a dead battery. Intelligent battery charging ensures the optimum charge rate as a function of battery level, resulting in minimum charge times. The rugged, unique dual case design provides the ultimate protection for a portable instrument and a clip-on lead pouch ensures that leads remain with the instrument at all times. The case lid is removable for improved terminal access. IP rating is IP65 with the case closed preventing water/dust ingress. High reliability and safety are built in; all models are safety rated to CATIV 600 V and are double insulated.

Five preset voltage ranges are provided in insulation test mode, plus a user settable lock voltage range. Any selectable test voltage may be locked and restored via the selector switch, thereby increasing efficiency of commissioning and repetitive tests. Preconfigured diagnostic tests include Polarization Index (PI), Dielectric Absorption Ratio (DAR), dielectric discharge (DD), Step Voltage (SV) and ramp test.
