The GF302D three-phase power calibrator and tester is used for the adjusting, checking and verification of measuring instruments such as; electricity meters, frequency, voltage and current protective relays, current transformers and clamps, active and reactive power meters, phase meters, frequency meters, ammeters, voltmeters, transducers, monitoring systems and power quality analyzers.
The GF302D is a single/three phase source of AC current and voltage with an accuracy class of 0.02 or 0.05, and programmable values for harmonics. It generates voltages up to 560V in sub-ranges 70V, 140V, 280V, and 560V. Current is available up to 120A in sub-ranges 0.5A, 6A, 20A, and 120A. Frequency ranges from 40Hz to 500Hz, and phase angle from 0 to 360°. In a single phase connection it can generate current up to 360A.
The GF302D can automatically obtain the error characteristics for measurement values and time characteristics of protection relays electricity meters, standard S0 impulse input is used with the possibility of a photo scanning head connection. When testing transducers, current transformers and clamps, a DC input with ranges 10V/20mA and an AC input with ranges 10V/100mA/5A is used. For protective relay testing, three timers with start/stop inputs and resolution 1ms are utilized. Two additional binary outputs are used for operate/standby calibrator state signaling.
The calibrator is controlled by means of a personal computer running a Windows operating system with meter test system software installed.
The Model GF302D provides the functions required to fully test power quality meters. Harmonics and interharmonics may be added to both the voltage and the current outputs. In addition, all outputs may be configured to reproduce sags, swells and interruptions. Other power quality related phenomena such as flicker and notching may also be simulated.
The Model GF302D facilitates the testing of all types of energy meters by delivering precise, user defined quantities of energy to the meter under test. The Model GF302D is also able to accept a pulse input for testing meters equipped with this type of output. The Option GF302D Optical Rotation Detector may be used to measure the rotation of an electro-mechanical energy standard. Alternatively, the Option GF302D, Optical Port Adapter, may be used to access an energy meter's optical communications port. The Model 8100 may be used with the Model GF302D2 six channel counter/comparator to test up to six energy meters simultaneously. When used in the external energy reference mode, all UUT's may be simultaneously calibrated against a single external energy standard.
A menu-driven front panel and simple intuitive controls make the Model GF302D extremely easy to use. Output settings and menus are displayed on a large color LCD display. Power settings may be expressed in units of Volt-Amperes, Watts or VARs. Similarly the phase angle may be expressed as either degrees or power factor. Such flexibility allows the Model GF302D to be configured to meet the specific requirements of any user. A compact rugged design makes the Model GF302D ideally suited to a wide range of operating environments from the laboratory to the factory floor.
Unequaled performance, simplicity of operation, and flexible system configuration make the Model GF303D today's standard for power and energy calibration.
