Clarke-Hess Communications Research
The Model M151 is a stable high current calibrator up to 120 A. Basic accuracy is 0.035 %. It can be controlled viaRS232 or GPIB interface. The Model 151 can function in a simulated amplifier mode to increase the current capabilityof any multifunction calibrator. It is suitable for power meter calibration because it can be synchronized with the inputsignal not only in amplitude but also in frequency and phase. The current terminals are isolated up to 450 Vpk againstcase (protective earth).

Single-Phase Transformer Winding Resistance Meters
RMO-TD Series
-
Using the most advanced switch-mode technology available today, the RMO-TD series is ideal for winding resistance measurements of inductive objects. Transformer resistance meters and tap changer analyzers are perfect for testing:transformer windings (power transformers, distribution, autotransformers),all types of tap changers,generators,electrical motors,high-current busbar joints,cable splices,and welding joints.In addition, transformer demagnetization can also be done with all RMO-TD instruments.The RMO-TD series contains 3 models, with maximal test currents from 25 A (RMO25TD) to 60 A (RMO60TD).The three independent voltage sense channels enable testing of three windings in series. This enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.All RMO-TD transformer resistance meters have a built-in tap changer control unit. It enables remote control of on-load tap changer (OLTC) directly from the device. In order to make the most out of this feature, DV-Win software is included which can be programmed to do everything automatically – running winding resistance tests and changing OLTC tap positions.The DV-Win software also enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test.All results can be exported in the report format.

Isolation Transformers
-
Osborne’s Isolation Transformers are used to step-up, step-down and isolate voltages in single phase circuits. Isolation may be used to provide output circuit immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the input system. The isolation can allow separate grounds on both the input and output sides of the transformer. Osborne also designs with a range of electrostatic shielding to provide several levels of noise immunity.

Flexible Current Sensor Probe
CTA
-
The CTA current sensors convert ac current to an isolated 0-5A current with available ranges from 100A to 10,000A. Because the current sensors are flexible split core, installation is possible without shutting down the LV electrical supply, avoiding expensive down-time costs. Typical applications are retrospective energy monitoring in factories, offices buildings, process control data logging systems, where power, energy and current monitoring is important. Typical applications are factories, offices buildings, ac/dc VFD drives, welding, power conversion and power distribution. For all CTA current sensor models, a NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All CTA sensors use UL94V0 or CSA approved materials. The CTA flexible current sensors are suited to permanent or semi permanent installation. The coil sensor is durable, lightweight, flexible and will easily clip-around a power cable. The 5A output from the CTA current sensor connects direct to installed metering, rotary metering or current transducers.
