3 CHANNEL TIME ANALYSER FOR CIRCUIT BREAKER

NTPL MAKE 3 CHANNEL TIMEANALYSER FOR CIRCUITBREAKER

TYPE NTT3CHCBTAR2

Theabove Time Analyzer is suitable to check simultaneous operation in threedifferent channels of 3 phase Power Circuit Breaker. The instrument is portableand is made with extensiveuse of integrated circuits to achieve accurate, long and trouble free service.

TECHNICAL FEATURES

Mains Supply                              230 volts +/- 10% 50Hz single phase AC.

No. Of Channels                         3

Time Measurement                    0 to 999.9m Sec., Resolution 0.1ms

Display                                        4 digit display for each channel.

Accuracy                                    +/-1% +/- 1 digit.

Operation Mode                           Opening or closing of potential freecontact.

Latching                                       Thisfacility is available for only clean signals of contact closing and                                                          opening withoutbouncing.

Reset                                            Bypush button switch.

The Timer will be providedwith CLOSE OPEN  and CLOSE-OPEN (C-O) push button switch incorporatingcontrol arrangement for supply of Power Source to CLOSE and OPEN coil ofCircuit Breaker under test and simultaneous start operation of the TimeAnalyzer. The timer stops with the change of status of the main contact withfeedback (potential free) from the main contacts of the circuit breaker.

The Power Source to the CLOSE and OPEN coil can be provided at extra cost by NTPL with following specifications
