Relay Test Set

GENERAL SPECIFICATIONS

Power Supply

Mains supply: 220 V ± 15%; 50-60 Hz.

Main Generator

The main generator shall have three outputs: currents, voltage AC, voltage DC with provision of generating at maximum power or at reduced power.

On all outputs the capability of - Current Ranges: 10, 40, 100 A. Output power: 800 VA. AC voltage range: 250 V. Output power: 500 VA.

DC voltage range: 300 V. Output power: 300 W.

Auxiliary AC Voltage

Output ranges: 65 – 130 - 260 V. Output power: 30 VA.

Auxiliary DC Voltage

Ranges: 130 V and 240 V.

Power: 90 W at full range; max. currents: 0.9 A @ 130 V and 0.45 A @ 240 V.

Timer

The timer shall have two inputs, START and STOP.

Inputs level: Normal Open or Normal Close. Clean or under voltage, maximum 275 V DC. Timer ranges: 9.999 s; 99.99 s; 99999.9 s. Accuracy: ± 0.005% of value ± 0.01% of range.

Auxiliary Contact

Two auxiliary make and break contacts shall have a delay from 0 to 99.99 s with respect to test start. Contacts characteristics: 5 A; 250 V AC; 120 V DC

Output Measurement

The display: AC current (AC or DC voltage); auxiliary AC voltage; auxiliary DC voltage. Accuracy, DC: 0.5% of reading ± 0, 1% of range; AC: 1% of reading ± 0,2% of range.

External Input Measurement

Input current ranges. 20 mA or 10 A, AC or DC. Accuracy, DC: 0.5% of reading ± 0,1% of range; AC: 1% of reading ± 0,2% of range. Maximum input voltage: 600 V, AC or DC.

Test Control

Selections, for the test of over- or under-(current, voltage.) relays. . OFF: main outputs not generated;. ON: all outputs generated;. From OFF to ON + time: all outputs shall be generated and timer shall start; at STOP, outputs are removed and time shall be displayed. . From ON to OFF + time: outputs shall be removed and timer shall start; at STOP, the time shall be displayed. - Reclose test.
