General Information
This section familiarizes the operator with the features and specifications of the
PFT Series of Power Frequency AC Test Sets manufactured by HIGH VOLTAGE, INC.
Features and Specifications
The PFT Series of AC hipot test sets provide continuously adjustable output voltages for the GO/NO-GO
testing of high voltage insulation. Earlier versions of the PFT Series were equipped with operator controlled
capacitive compensation switches to minimize input primary currents. The new simplified controls incorporate
this feature transparently.
Standard features of the PFT Series of include:
•
Continuously adjustable output voltage
•
Fixed overload, factory set to 120% of variable transformer rated output current
•
“Zero Start” and External Interlock provision
•
Secondary connected dual-range voltmeter
•
Shielded output cable (50 kV and below) precludes unnecessary insulated support of the cable
•
One piece portable design (50 kV and below)
•
Transit protected meters prevent meter damage between test sites
•
Capacitive load compensation incorporated to allow up to 3 KVA output power with less than 15
Amperes input line current.
•
Fault Burn Reactor (Optional)
