PXI Dual 4 to 1 RF MUX SMB 75 Ohm
40-832-002
The 40-832-002 is a 75 Ohm 4 to 1 RF MUX with 2 banks in a single PXI slot. It has been designed to exhibit low insertion loss and VSWR through the use of modern RF relay technology at an affordable cost. Each MUX has been carefully designed to ensure excellent and repeatable RF characteristics to frequencies of 3GHz with each path having a nominally equal insertion loss. The design of the 40-832 minimizes the injection of noise and unwanted signals into the signal path by careful attention to the mechanical and electrical design.

Relay Test Set
Relay testing equipment is a portable apparatus designed for checking the operating characteristics of protective relays on site. Rr Relay Testing Equipments are designed to facilitate routine test or periodic maintenance test of relays by simulating (as early as possible) fault conditions under which the protective relays are required to function. There are several approaches to the method of testing relays on site. The Relay Testing Equipments are secondary injection type and are intended to be used to test the relays after isolating them from live systems, either physically or electrically.

20Hz Generator
Signals & Systems India Private Limited
In order to implement a 100 % stator earth fault protection based on subharmonic injection, a 20Hz voltage is injected into the generator star point. The 20-Hz generator SGEN-1001 is used in combination with the Band Pass Filter SBPF-1001 in the Stator Earth fault protection. The injection can be performed by connecting the SGEN-1001 and the SBPF-1001 to the load resistor of an earthing or neutral transformer. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. From the driving voltage and the fault current, the protective relay determines the fault resistance.

Monitoring Relays
A Monitoring Relay is a protective control device. The basic functions are to receive input signals, monitor and determine them, and output an alarm signal if a set value (threshold) is reached. Monitoring Relays monitor power supplies (voltage, current, power, phase), temperatures, and other analog signals and detects abnormalities in machines and equipment by determining values against alarm thresholds.

Sensing Resistors
Resistive Voltage Dividers
NGR Sensing Resistors are attached in parallel to the neutral grounding resistor. The sensing resistor allows a protective relay to detect a resistor failure in a continuous manner. Sensing Resistors are used in combination with neutral grounding resistor monitor relays. The relay measures neutral grounding resistance, neutral grounding resistor current and neutral to ground voltage. The relay continuously measures neutral grounding resistor ohmic value in an unfaulted system and it trips on if neutral grounding resistance varies from its calibrated value.

Circuit Breaker Analysis Systems
When a fault such as a short circuit or current overload is detected by a protective relay, a trip impulse is sent to the circuit breaker. The circuit breaker must function as specified and interrupt the current as soon as possible or severe damage may occur. The damage caused by a malfunctioning circuit breaker can often be catastrophic, resulting in significant damage to the electrical system.
