Microhmmeter series TC



MICROHMMETER TC-1

The compact instrument is designed for the measurement of the electric resistance to the direct current of various units, switchboard panels, small electric substations, electric apparatus and others, including the breaker contacts, bolted and soldered joints of the electric system circuits under the conditions of the noise of electrical field with the potential stress of up to 20 kV/m.
The instrument power supply is provided by four batteries of AA type. The batteries are included in the supply package.
The instrument is registered in the State Register of the Measuring Instruments of RF. The measuring instruments type approval certificate RU.C.34.033.A. No. 52181.

Микроомметр ТС-3

MICROHMMETER TC-3

Microhmmeter TC-3 is designed for the measurement of the electric power systems interconnect circuit transient electrical resistance: aerial, oil-immersed and other contacts, disconnect switches, bolted and soldered joints under the conditions of the noise of electrical field with the potential stress of up to 30 kV/m (electric substations – up to 750 kV). The instrument and its superseded models (MMO-1, БС3-010 and others) have been efficiently operated by the fuel and energy complex companies in Russia, Belarus, Ukraine and Kazakhstan for somewhere about twenty years.
The instrument is registered in the State Register of the Measuring Instruments of RF. The measuring instruments type approval certificate RU.C.34.033.A. No. 52181.

izm-kabeli ts-3The customer receives the input measuring cable with the contactor switches providing the four-terminal connection to the monitored item, against the additional order. The edged contact points of the contactor switches allow gaining the reliable contacting with the item that has the surface covered with the paint or oxide film. The length of the measuring cable can be chosen from the range: 3, 5, 10 and 15 meters.


Микроомметр ТС-200

MICROHMMETER TC-200

Microhmmeter TC-200 is designed for the measurement of the electric power systems interconnect circuit transient electrical resistance: aerial, oil-immersed and other contacts, disconnect switches, bolted and soldered joints under the conditions of the noise of electrical field with the potential stress of up to 30 kV/m (electric substations – up to 750 kV).
The identifying feature of TC-200 microhmmeter is the possibility to take the measurements at the survey current of up to 200 A, which allows avoiding the oxide film damage on the contactor switch connector boundary.
The instrument is registered in the State Register of the Measuring Instruments of RF. The measuring instruments type approval certificate RU.C.34.033.A. No. 52181.
