100VA PHANTOM LOADS:MODEL 467B-30
This 3 phase phantom load is used for energising CT or Direct
connected Energy meters during commissioning or routine testing.
The 467B-30 can deliver over 100VA per phase at 100Amps / 1V.“Variacs” are used to adjust the current injection amplitude from zero
to full scale. Shrouded safety plugs and sockets are used to connect
the cables to the front panel. The input required is 240V/415V 3 phase,
4 wire and this is protected with a 3 pole circuit breaker. -
10A 3 PHASE PHANTOM LOAD: MODEL 462F
The Model 462F is designed for use with any field test set for testing polyphase CT meters.
It can be powered from the metering test block, and will test nominal 240V, 3 phase, 4 wire star connected L.V. meters or nominal 63.5V star connected H.V. meters.
It can also test nominal 110V, 3 phase, 3 wire delta connected meters.
This phantom load can be used with the Red Phase Instruments Model 679 and 679B polyphase meter testers, or any other meter tester.The 3 current outputs are variable from 0 to 100% in 1A and 10 A ranges in coarse (10%) and fine (1%) increments. Phase angle/power factor settings are available from 60º LEAD to 90º LAG in 15º increments

20A 3 PHASE PHANTOM LOAD:MODEL 473
Simple and easy to use 3 phase phantom load used in pre or post commissioning of metering and / or measurement products.
Easy way to determine correct installation and phasing of
equipment.
Supplied cable accessory is 4 metres long and is capable of providing 7.5 to 8 Amps of load current.
With shorter and thicker gauge cabling the 473 is capable of providing up to 20 Amps of load current per phase. -
PHASOR METER: MODEL 633
This complements the Model 632A, since the Model 633 reads phase angle, true rms voltage and true rms current in a circuit. This instrument is designed to demonstrate the properties of phasors and real/imaginary number notation for electrical engineering students. This instrument gives the phase displacement and magnitude of the parameter under investigation. The unit has filters to eliminate harmonic distortion affecting phase angle measurement.
The instrument has 500V and 50V voltage ranges and 10A and 1A current ranges plus a 500V range reference voltage input. Phase angle accuracy is typically 0.5º and voltage /current accuracy is 0.3% at 50 Hz, 20% distortion.

POLY-PHASE PHANTOM LOAD: MODEL 472
3 Phase, 4 wire 240V / 415V 50Hz + Earth
3 phase 10A circuit breaker used to protect the unit.
Neon indicators indicate which phase is live
Output configuration is switchable from star to delta.3 phase, 4wire star 240V / 415V nominal.
Maximum out is 0.7A, 160VA.
The output voltage is controlled by 3 “Variacs”, and is adjustable from 0-110%.
The output is not isolated from the mains supply.3 phase, 3 wire delta 110V nominal.
In this configuration the output from the 472 is isolated from the mains supply.
The N terminal is earthed to chassis and mains earth.
The output of VA and VC terminals is 110V nominal with respect to the N terminal.
The output voltage is controlled by 2 “Variacs” and is adjustable. -
QUAD AMMETER: MODEL 4014
The Model 4014 integrates four ammeters for the direct and simultaneous reading of 4 CT secondaries up to 10A during the setting up or checking of protection systems while they
are in service with normal 50/60Hz primary currents flowing.The two terminals of each channel of the Model 4014 are connected in series with the CT secondary with all other equipment in the loop or directly across the CT secondary.
The unit can be mains powered or run off its internal Ni-Cad battery which can last from 8 to 10 hours.
To re-charge, simply reconnect to mains power via an IEC power cord. -
WATT AND PHASE ANGLE METER: MODEL 632A
We have sold many of these simple, accurate and robust instruments to utilities, industry and educational institutions.
They are used for many purposes, from student instruction in the electrical laboratory to quality control in appliance testing.
The 632A has 50V, 160V and 500V voltage ranges and the current inputs are 1A, 3.2A and 10A.
Accuracy of power measurement is typically 0.5% and accuracy of phase angle is 0.5º.
