• The Human Machine Interface (HMI) allows the programming of automation features of the test set. All output meters are displayed on the LCD screen. Data acquisition and report generation of the test results are performed via computer and WIN TTS testing software with all required interface cables included. The HMI eliminates a large number of relays and meter wiring which increases reliability. All calibration functions are performed and component self-checks are achieved which aid a service technician in locating malfunctioning components in the event of a failure.
• Zero Start interlock with auto return of regulator to zero position
• Raise and Lower pushbuttons with Off Zero indicator
• Motorized control of output voltage with adjustable rate of rise
• Control power key switch with indicator
• EMERGENCY OFF mushroom switch
• Motorized tap selector with indicators
• Auto-ranging wattmeter and voltmeter with direct readout
• 15 foot (4.5 meter) output leads with boots and clips (separate power and measurement leads). Jacks for output leads are recessed for operator safety; leads are removable for operator convenience
• Fork truck and overhead lifting provisions.

Phenix Technologies’ Single-phase Transformer Test Systems are designed to provide voltages and currents to test single phase distribution transformers.

The size of transformers which can be tested will vary with impedance. Test systems equipped with optional high voltage taps will allow testing of transformers with higher impedances and/or higher secondary voltages.

The precision metering system complies with DOE efficiency and international transformer standards.

Testing will ensure that a transformer meets purchase specifications and will perform adequately after installation.

Perform the following tests in accordance with ANSI / IEEE C57 and IEC60076 standards:

• Excitation Current Measurement
• Excitation Loss (No-Load or Core Loss)
• Impedance Voltage Measurement
• Copper Loss (Load Loss)
• Temperature Measurement
• Temperature Measurement (Heat Run) (via models TTS20-1, TTS30-1,TTS50-1 only)

Additional testing can be performed when the following options are added:

• Applied Potential Test with the addition of an AC Hipot
• Induced Potential Test with the addition of a Motor Generator Set
• Turns Ratio Test with the addition of a Transformer Turns Ratio Test Set
• Winding Resistance Measurement with the addition of a Winding Resistance Meter

Environmental Conditions

• 10-40°C, indoor/outdoor in fair weather
• Humidity <95% non-condensing
• Altitude <3300 ft (1000 meters)

Options

• Applied Potential Testing Capability via AC Hipot, cylinder-type
• Induced Potential Testing Capability via Motor Generator Set includes ON/OFF controls and frequency meter built into the control panel
