PTE-100-C secondary injection test set

Single-phase AC/DC Relay Test Set with Variable Frequency5
This is incorporated in PTE-100-C cover lid, and allows, regulated AC voltage, frequency, and phase angle.

PTE-100-C Series: a leader and world reference for protection relay testing, based in variac output regulation. The smallest and lightest single-phase secondary injection test set in the market.
With IP-65 rated case, outstanding 1000 VA output power (for wide application range of protective relay tests, including the higher power demanding electromechanical relays); the PTE-100-C integrates many measurement and testing functions, and comes with a large set of upgrading options and accessories, for accurate and unbeatable fast testing at competitive price.

A mus The values which are presented in the LCD display are highly accurate, easy to read, and independent of the injection made by the PTE-100-C base unit.
The display shows continuously the phase difference between the voltage and the current injected, and can be adjusted during the test with an accuracy of 0.1º. This facilitates the test for directional relays or reclosers and synchronizing relays, etc.

The protection tests based on frequency are simple and direct, due to the variable frequency between 40 and 70 Hz incorporated in the module.
