 FUNCTIONS: USE AND DESCRIPTIONS 

Throughout this section a detailed description of the use and procedures for the PTE-50-CET will be 
given. This unit has been designed to be used as a portable three-phase unit to test any kind of relays, as 
a stand-alone unit or interconnected to other auxiliary units. All the functions that are incorporated in this 
unit were designed to easily test the relays. This is achieved, as all functions are located on the front 
panel in a MANUAL mode, which before required test units, which were programmable by an external 
computer. 

Furthermore, the PTE-50-CET, and thanks to the BUS-PTE, can be easily interconnected to other units in 
the PTE range, making the specific functions for relay testing, much more simple and effective. 

4.1.

 TIME MEASUREMENT 

The timer is normally activated by a power output, despite it is current or voltage. For this reason, 
when it is stopped by a “STOP” signal, it holds the actual measurement in the display. 

The resolution of this timer is 0.001 s, which is sufficient to test almost any protection relay. 

4.1.1. SIGNAL 

MONITOR 

It is here where the timer receives the signals from the relay being tested and this is shown in the 
optic LED indicator marked MONITOR. 

The 

Signal Monitor

 is ACTIVATED in the following conditions: 

1.  When there is a VOLTAGE PRESENCE between the common tap and the voltage tap (red). 

This voltage can be between 3 to 250 V in ac or dc. This input is protected with a fuse clearly 
marked. 

2.  When there is a CLOSED FREE CONTACT between the common tap and the contact tap 

(green). This input is protected with a fuse clearly marked on the front panel. 

In both of these conditions, when the 

Signal Monitor

 is active a red LED will light up. 

 

NOTE: 

When connecting the monitor signal to the free contact tap (green) be sure that it is really 

free from voltage as the protection fuse will break immediately. 

 

4.1.2.  TIMER MODE SELECTION 

The timer mode is selected with the 

Mode

 key and the following modes can be selected 

•

  Mode 1:  

Start: 

By the injection of current or voltage. 

Stop: When 

the 

Signal Monitor

 is activated. 

•

  Mode 2:  

Start: 

By the injection of current or voltage.
