About the Current Viewing Resistor (CVR) / Non-Inductive Co-Axial Shunt Resistors
Our range of CVR's are non inductive high frequency coaxial shunts designed to operate over a wide bandwidth, with both AC and DC power systems, especially where phase angle is a consideration, crucial during impedance measurements and power calibration systems. Very useful for adding or extending the current range of Frequency Response Analyzers and Multimeters. CVR's can be used with phase angle meters, where phase angle between voltage-voltage, voltage-current or current-current is required, ideal for phase protection, power meters, wattmeters, energy meters and current transformer calibration.
CVR's are rugged high frequency resistors designed to sustain very high peak power and current inputs generated by capacitor banks, pulse generator systems and steady state current loads. Their linear response over a broad frequency band provides an accurate indication of current magnitude free from inductive components. Inherent in CVR design is a coupling between the major electrical parameters of resistance, bandpass, energy capacity and wattage rating. This means we provide a wide ranging series of standard units covering a broad range of specifications.
WATTAGE RATING
Although most CVR's are designed primarily for surge current measurements, their rugged construction and their low temperature coefficient resistive elements have made them ideally suited to a number of steady state applications. An average wattage rating applicable to continuous current loading is thus quoted for each resistor series. Care should be taken in circuitry involving either AC or high duty cycle pulse currents that this rating not be exceeded, since CVR damage by overheating can result. If requested we can supply resistors with special construction which will increase the standard wattage rating to a high value depending on the model.
FREQUENCY RESPONSE
Bandpass of a CVR is essentially flat from DC to an upper limit determined primarily by skin effect in the resistive element. Associated bandpass is based on a measured 10% to 90% risetime response to a step function of current produced by a coaxial line pulse generator. The di/dt of the test pulse exceeded 10^12 amps/sec.
RESISTANCE VALUES
Unless otherwise specified, resistors are supplied with resistance tolerance of ±4% of nominal value. In addition, a Kelvin Bridge determination of its exact resistance, accurate to ±0.2% is supplied with each unit. The thermal coefficient of the coaxial shunts is 8-10 ppm/degC. A wide range of special resistance values for any of our standard units can be supplied.
MECHANICAL DESIGN
Case construction of all coaxial current viewing resistors is silverplated brass. Standard output signal connector is BNC with other connectors available. Large coaxial CVRs utilize a high current flange and coaxial threaded stud input connections. Powertek's flat configuration CVRs, the Series W, originally developed for flat plate transmission line installation, are available in a wide range of unit widths and input configurations and have been found to be particularly useful in applications requiring resistors with extreme energy and wattage ratings.
WORLD-WIDE TRACEABILITY
All measurements made using the CVR coaxial shunts are traceable to National and International standards; through the measurement standards of Powertek. All CVR coaxial shunts are supplied with a certificate of conformance necessary for quality assurance standards such as IEC17025/ISO9001. Independent measurement certification is possible using UKAS, A2LA or Z540/NAVLAP certificate.

What is a Differential Voltage Probe?
A differential voltage probe measures the difference in voltage between two points on the device under test (DUT). However, these two points may be floating, meaning they not ground referenced - typically found in switching power supplies or similar power electronic inverters. As the name suggests a Differential Probe uses a differential amplifier along with sufficient input impedance often comprising several MOhms. A differential probe presents little influence on the DUT's operation and allows safe monitoring of system voltages. Often it is crucial for safety when measuring high voltage signals in non-ground-referenced circuits. An important distinction is that a differential probe does not use galvanic isolation.

Differential Voltage Probe Applications
High voltage transmission is often thought of when thinking of high voltage applications, however there are many applications that require a high voltage power source. The definition for high voltage applications varies by industry and region. The IEC defines high voltage as anything above 1kV for AC and above 1.5kV for DC, in automotive engineering high voltage is anything above 60V. The primary use of high voltage outside of transmission can be found in the industrial, scientific, medical and imaging fields.
High voltage applications within the medical field include:-Electrophoresis (a technique used to separate proteins, and nucleic acids such as DNA/RNA based on their size and electrical charge)
PCR (polymerase chain reaction) tests, and DNA sequencing
X-ray tubes require a high voltage to be able to generate x-rays used for imaging
Image intensifiers (where photomultiplier tubes also use a high voltage field to accelerate photoelectrons). This effectively multiplies the incoming light signal

What is a Static Frequency Converter?
As the name suggests a Static Frequency Converter or SFC, changes from one power frequency to another, usually at a fixed installation. In addition, most SFCs will allow a change from one voltage to another. Applications include maritime docks, avionics testing, airport ground power and appliance testing.
Start discussion about your SFC needsThe Powertek static frequency converters serve as a popular frequency changer: AC Power 50Hz to 60Hz, 60Hz to 50Hz or 50/60Hz utility power to 400Hz. Specialist frequency conversions are possible 16.67Hz/25Hz/100Hz. Our Ptk-33000, Ptk-FCM and Ptk-SFC series static converters utilize a built-in rectifier, converting incoming AC power into DC, then inverting the DC to the required frequency and voltage based on IGBT switching and a built-in isolation transformer. The Ptk-FCM series has many advantages, making them ideal for export product testing or operational test of imported equipment helped with their command and control interfaces. Applications such as the testing of military/avionics equipment, typically 400Hz electronics operated in aircraft, where maximum and minimum conditions are simulated. For aircraft ground power, fixed wing and helicopter applications, GPU or a military vessels, a variety of formats are possible including dual o/p combinations 28Vdc/120Vac 3ph 400Hz GPUs
