DC Insulation Testing
Diagnostic insulation testing today represents over a hundred years of constant development. When Sydney Evershed pioneered the first insulation tests in the late 19th century, the only measurable values were insulation at 500 volts and a basic continuity check. However, measurement techniques have continuously evolved to keep pace with new insulation technologies. From electronic design and household wiring to generators and power transmission systems, all different kinds of insulation must operate at a safe minimum value.

Transformer Winding Resistance Meters
TWA Standard Series
The TWA standard series instruments are designed to measure the resistance of six coils and simultaneously analyze the three-phase tap changer on load of the primary and secondary transformer coils (provided by model TWA40). This is done in a single cable configuration, with test currents up to 40A. Each transformer configuration has a special measurement algorithm that is optimized for rapid stabilization of test results. The TWA instruments generate a true DC current without ripple. Both current injection and magnetic circuit energy discharge are automatically regulated.

Resistivity Meter
Model 2180
The unit is compact and lightweight. The basic system is 7″ wide by 2.5″ high and 12″ long. When measurements are needed below approximately 100 micro-ohm-centimeters, the basic system is piggybacked onto a second enclosure that houses a power amplifier with a current gain of ten. The combined unit measures 7″ wide by 5″ high and 12″ long. The combined unit weighs 11.5 pounds. Two short cables interconnect the two enclosures for powering the power amplifier and routing the signals to the fixture or four point probe. The front panel of the basic system includes a 32-character backlit LCD display and a set of function keys. An easy-to-use menu will allow access to user defined parameters such as sample thickness, sample volume, and calibration constants; upper and lower alarm limits, relative measurements, and several others.

Insulation Tester
Shenzhen Graigar Technology Co.,Ltd.
Testing the integrity of insulation requires measuring its resistance to current flow across it. A high level of resistance means that very little current is escaping through the insulation. Conversely, a low level of resistance indicates a significant amount of current may be leaking through and along the insulation.

Contact Resistance Meter
The Motwane Manufacturing Company
High contact resistance values are a definite cause of the failure or less than optimal performance in a wide variety of electrical devices. Contact resistance testing is therefore most critical to measure the resistance of electrical connections in switching devices, circuit breakers, isolators, busbars, relays, joints, connectors, cables, and cable joints. The device helps to find destructive or corroded contacts and hence protects substation devices from damage.

AC Insulation Testing
AC insulation tests are a popular response to the increasingly demanding industrial, power and domestic marketplaces. Insulation materials have had to become more efficient to keep up with demand; more efficient equipment requires less insulation material to meet the minimum acceptable value of insulation resistance. In turn, cables have become smaller and lighter. However, under certain higher stress testing conditions such as DC testing, cables like Crossed Linked Polyethylene (XLPE) can quickly degrade.
