Megger Group Ltd.
When a high current passes through a pair of mechanically independent metallic contacts, the resistance must be as low as possible. An increase in resistance can lead to additional degradation, as I2R losses will cause local heating of the contact surfaces. Our range of micro-ohmmeters measure both steady state and dynamic low resistance values. With test currents up to 600A available, logging and trending are also available on some models. We ensure that our Contact Resistance tests sets are portable, making them suitable for field measurements. Our contact resistance testers’ portability makes them ideal for a vast range of resistance testing across the entire LV, MV HV and EHV spectrum.

PRK-130 -
Prostat Corporation
The PRK-130 is an advanced kit that includes the PRF-930 Powder Resistance Fixture for measuring the bulk resistance of powder and granulated materials. Test material is placed in the cavity between the measurement plates. Once a measurement has been made in ohms, a fixture calculation, or correction factor, converts the resistance measurement to volume resistivity in ohm-cm.

ERT-1501 -
Neutronics Manufacturing Co.
Electronic Digital Earth Resistance Tester is direct replacement of the conventional hand generator type tester. It is designed for measurement of the resistance of earthing used in the electrical equipment as well as for measurement of ground resistivity. It can be used for measurements of the other low regular and liquid resistances. It can also be used for measurement of voltage AC, voltage DC and resistance. This instrument finds wide application for testing earthing installation in power based industries, telecommunication networks and electrical traction systems etc.

MR 270 C-A -
Schuetz Messtechnik GmbH
The MR270C-A is specially designed for electric resistance measurements in cable industry applications and inductive loads (transformers, motors). It is perfectly fit both for measuring the meter resistance in connection with a corresponding resistance measurement holding device or for final acceptance control of power cable reels. In the case of cable reels, which often have a cable length of several kilometers, both the compensation of the inductive component and the ability to perform measurements in the presence of high noise levels are important. This also applies to the winding resistance of transformers and motors.
