HV-2
High Voltage System

Tests Power Transformers for Continuity, Ratio and Phase. Applied and Induced Potential and No-load Losses.
14 Conductor Switching Matrix will test 7 individual windings, 13 taps of one common winding or some combination thereof. (10 Amp current limit)

The System Control is Windows/Visual Basic based. Menu screens allow full selection of test parameters and sequence. Low voltage tests can be performed first, allowing defective parts to be rejected without proceeding to time consuming induced Potential dwell routines. Test data labeling and data acquisition software can be easily added to the system.

The test system consists of the following hardware:
486 Computer with I/O 488 interface and parallek I/O card
Monitor, Keyboard, Mouse (external to Rack)
Associated Research 6550 DT 5 KVAC HiPot Tester
Hewlett Packard 34401 Multi-meter
2 each 1kW Power Amplifiers
14 Conductor Switching Matrix
Ratiometer/Polarity circuits
20 Hz-65 KHz Signal Generator
19" Rack Mount Cabinet

By using a modular construction, the HV-2 is completely adaptable to a variety of testing requirements. By using the IEEE 488 bus, additional components can be readily added to the system. The Switching Matrix, the core of the power system, is designed to be reliable and easily maintained. All parts are guaranteed by iem for a period of one year.
