Circuit Breaker Test Equipment

Circuit breaker testing equipment is very important for testing the circuit breaker. In this article, we will discuss the equipment used for testing the circuit breaker.

The following equipment is used for testing the circuit breakers.

  • SF6 Gas Leakage Detector
  • SF6 Gas Evacuation and Filling Device
  • PD Monitoring System
  • SF6 Gas Purity Analyzer
  • SF6 Filling, Evacuation, Filtering, Drying & Storage
  • Contact Resistance Meters
  • SF6 Gas Dew Point Meter
  • Circuit Breaker Operation Analyzer

SF6 Gas Leakage Detector

SF6 Gas Leakage Detector pinpoints the leakage of SF6 gas in high voltage switchgear. It facilitates the maintenance crew to do preventive repairs to avoid complete breaker failure.

Circuit Breaker Testing Equipment

The proper functioning of the circuit breaker depends on the proper working pressure of the SF6 gas. The low level of gas causes the breaker to remain in its last state. Therefore, it is very important to detect minor gas leakage.

Thus, it is a very important device for close monitoring of the healthiness of the SF6 breaker.

SF6 Gas Evacuation and Filling Device

SF6 Gas Evacuation and Filling Device

SF6 Gas Evacuation and Filling Device is a portable handcart (with optional storage cylinder) designed for-

  • To evacuate
  • To vacuum and
  • Refill small quantities of Sulphur Hexafluoride (SF6) in switchgear and breakers.

SF6 Gas Purity Analyzer

The Gas Purity Analyzer checks the quality and purity of SF6 gas during the recycling of the gas. The quality of gas in gas-shielded switchgear used in power and industrial plants must be perfect.

SF6 Filling, Evacuation, Filtering, Drying & Storage

SF6 Gas Filling, Evacuation, Filtering, Drying & Storage Unit transfer the SF6 Gas from one point or external storage cylinders. The main purpose of this is to avoid venting the gas into the atmosphere. Thus, this process enables Greenhouse gas reduction.

Circuit Breaker Testing Equipment

It is possible to remove the hazardous contaminants from the SF6 gas by the use of suitably designed filters and scrubbers. And, it is possible to use the recycled SF6 gas, thus minimizing the requirement of purchasing new gas. Therefore, perfect recycling is a must for avoiding more uses of SF6 gas.

SF6 Gas Dew Point Meter

SF6 Gas Dew Point Meter

SF6 Gas Dew Point Meter measures the moisture and dew point accurately over a wide temperature range in SF6. The moisture causes insulation value to deteriorate. Therefore, the dew point monitoring is very important for a long life of the breaker.

PD Monitoring System

Partial Discharge (PD) measurement is the most important test for the assessment of the remaining insulation life of the electrical equipment. Thus, the PD monitoring ensures the remaining usefulness of the equipment by measuring the health condition of the insulation system.

PD Monitoring System

It is possible to monitor the partial discharge on a continuous basis. Online partial discharge monitoring is a powerful tool to protect and optimize the performance of the assets.

The online PD Monitoring gives a powerful insight into the health condition of the insulation system. Thus, it is possible to detect the fault at the very beginning, avoiding the breakdown of the circuit breaker. The following are the advantages of PD monitoring.

  • Pre-failure preventative action
  • Significant reduction of costs
  • Reduction of inspections and maintenance
  • Prevention of expensive catastrophic failures
  • Improved quality and reliability of power supply
  • Extension of plant/transformer life

Contact Resistance Meters

Contact Resistance Meter measures the contact resistance of the circuit breaker.

Contact Resistance Meters

The circuit breaker contacts have very low resistance, in order of micro-ohms. The contact resistance meter measures the low resistance accurately.

Circuit Breaker Operation Analyzer

Circuit Breaker operation Analyzer is a useful device for the maintenance and commissioning of medium and high voltage circuit breakers.

It measures the static and dynamic contact resistance measurement with an accurate timing speed and motion analysis.

Circuit Breaker Testing Equipment

It measures opening and closing time and records graphs of coil currents and displacements of moving contact of a circuit breaker.
