Description

The equipment is extremely compact, and contains all the functions necessary for current and voltage relays. It incorporates various measurement functions such as a voltmeter, ammeter, frequency meter, as well as measures apparent power, impedance, and internal and external phase angles. From the front panel controls, the maximum output injection can be limited, used for example in testing instantaneous overcurrent relays. Injection time can also be limited, useful to safely test reclosing devices.

The PTE-100-C can communicate with a PC via the serial port RS-232, and can be connected to other PTE units via the BUS-PTE.

All the PTE equipment are supplied with an adjustment and calibration software, which allows closed case calibration, with the only requirement of having a standard reference measurement equipment.
