Test Single or Three Phase Cores!

• Now Available!

The Manual Test Rig is an industrialised manual version of our Test Bench developments to date. Currently our Test Benches test only single phase cores.

The Manual Test Rig is a three phase unit with quick connect cabling to enable fast and accurate testing of 3 phase cores. Any type of 3 phase core: Evans, 4 loop or flat stack can be tested for magnetising current and power loss using the manual variac. Single phase test leads convert the unit into a simple single phase test rig with the change of a test lead.

A spread sheet tabulates the required induced voltage needed for a specific number of turns around a particular core size (entered) for various flux densities. These target voltages allow the operator to energise the core to set flux densities and read off the actual voltage, current and instantaneous power.

The results are entered into the spreadsheet producing a graph showing the interpolated core performance vs flux density for both Power Loss (Watts) and Magnetising Force (A/m).

Available measurements for each channel include:

• Volts

• Amps

• Watts

• VA

• Var

• Power Factor (PF).

• Three phase measurements can be displayed either as individual phases or as the summation of all three phases (default).
