Megger MTO300 Series - The Industry's First Six Winding Transformer Ohmmeters

Megger MTO300 series transformer ohmmeters measure all six windings of a three-phase transformer automatically without changing connections. With test current capability up to 10 A, they provide simultaneous winding magnetization to ensure fast, accurate results, and auto-demagnetization after test. And, by sharing the same lead set as Megger TTR turns ratio testers, they make transformer testing even more convenient.

Selected Features and Benefits

• Automated, eight-terminal/six-winding measurement capability – saves time and money by testing all windings in one test sequence, which means big reductions in disconnect/reconnect time and “ladder time”.

• Simultaneous winding magnetization – allows MTO300 series instruments to deliver reliable results fast, even on large transformers.

• Got a Megger TTR300 turns ratio tester? – The leads are the same as the MTO300 series. Connect once to test both turns ratio and resistance.

• On-load tap-changer testing – continuous operation with graphical display of winding resistance per tap, and test current change detection.

• Auto-demagnetization feature – removes residual magnetization of the transformer core after testing, making the transformer ready for SFRA or excitation tests, or for return to service.

• Automatic discharge for safety – active circuitry monitors both current and voltage leads to ensure safe discharge of the transformer after test, even if the power is lost.

• PowerDB compatibility – store, organize and archive your test data, and produce reports quickly and easily in almost any format.

• Two models to suit all users – The MTO300 is controlled by PowerDB software on an external PC while the MTO330 has its own on-board computer, keyboard and display.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to
