Cutler Hammer's 140D481G03 Offers Secondary Injection Testing You Can Rely On

A circuit breaker is a manually or automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. In addition to providing a means to open and close its contacts manually, a circuit breaker must automatically open its contacts when an overcurrent condition is sensed.

The trip unit is the part of the circuit breaker that determines when the contacts will open automatically.

In a thermal-magnetic circuit breaker, the trip unit includes elements designed to sense the heat resulting from an overload condition and the high current resulting from a short circuit.

Reliable Primary Injection Testing with the ETI PI-6000

Primary current injection testing is usually associated with high current and high voltage power distribution systems found in an electrical substation, or in a large industrial installation. The principle is very straightforward: a test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. By injecting a predetermined current into the circuit breaker, it is possible to determine whether the relay will trip at this current and, if so, how long the current needs to flow before the trip is initiated.

ETI PI-6000 High Current Test SetOne popular circuit breaker tester is the Electrical Test Instruments PI-6000 Circuit Breaker Test Set. The ETI PI-6000 is an advanced primary injection test set capable of testing circuit breakers up to 6000 amperes frame size.

Circuit Breaker Timer: An Electrical Test Equipment Add On

A circuit breaker timer is a device that is mostly used in conjunction with other circuit breaker test sets for diagnostic analysis of the circuit breakers. The circuit breaker timer is used as a simulation device to imitate the conditions of overload to measure different parameters or modes which include stroke, velocity, and contact times.

Circuit breaker test equipment is used for comprehensive and accurate testing which makes sure that the breakers function properly when exposed to a high magnitude of current passing through the circuit. Circuit breakers perform the task of breaking the current circuit in case of current overload. If the circuit breaker doesn’t perform properly, the high current may damage one cable, whole wiring, or the entire device. This calls for preventive measure in the form of regular testing of circuit breakers.

Secondary injection test kit is another piece of electrical test equipment that helps in testing the health of circuit breakers but doesn’t involve passage of large currents. Rather, low voltages are used for this purpose. No matter what the mode of testing is, it is necessary to carry out preventive testing and diagnosis of circuit breakers to ensure absence of critical issues and the nagging fear of expensive electrical device failure.

Testing of Electromechanical Protective Relays

Protective relays usually attached to medium voltage circuit breakers to detect abnormalities in the current flowing in the electrical system. When a protective relay detects a problem, it isolates the fault with minimum disturbance to the electrical facility. Protective relays are designed to respond quickly on power events like abnormal influx of current in the electrical circuit.

The common type of protective relay is the electromechanical one. The mechanical assembly may become defective after a while due to thermal/electrical stress and the accumulation of contaminants like corrosion or dirt. In an industrial setting, regular preventive maintenance should be conducted once a year to ensure reliable operation.

Protective Relay Testing Procedure

The proper cleaning and testing of protective relays is usually found on the manufacturer's user manual. However, if you do not have the manual of the device, you can do the procedure below to test medium voltage electromechanical devices. The information was taken from various manuals and testing publications to ensure consistency with the acceptable testing standards.

1. Visual Inspection

1a. Remove the relay cover

  • Inspect the gasket of the cover
  • Inspect for cracks or frame tightness
  • Clean the covers and glass thoroughly

1b. Remove the relay assembly from the case

  • You should short circuit the CT terminals for safety
  • Open all of the trip circuits

1c. Foreign objects like metal bits and dust should be remove from the case and the relay. These may cause problems on the mechanical parts and cause erratic operation of the relay.

1d. Blow dust by blowing air gently using a hand syringe.

1e. Metal bits or corrosion should be remove from the magnet poles or disc using a brush or magnet cleaner

1f. Hold the relay up to the light to ensure that the gap has good clearance and that the disc does not rub.

1g. Check for moisture problems. If you see rust spots on the relay, it is important to check if the relay is in proper operational environment. Moisture can cause severe corrosion and problems in the mechanical components.

1h. Check for loose connections. Taps, screws, bolts, nuts and pivotal joints should be tight.

1i. The bearings should be smooth. To check, the disc is rotated manually to close the contacts and letting the action of the spiral spring to the relay disc to its deenergized position. You should observe for smoothness and should not be sluggish. You can clean and put oil on the mechanism. However, if cleaning and oiling fails, the relay must be reconditioned or replaced.

1j. The operation of targets should be manually checked. This is done by fitting the armatures and checking if there is a showing target.

1k. The relay coil must be inspected to ensure that it is not subjected to high currents for a long time.

1l. The components that touch together during a relay's normal deenergized position must be cleaned. This is to prevent the relay from getting stuck or operate erroneously especially on low current faults.

2. Electrical Testing

2a. Disconnect the relay from the trip and power circuits for testing.

2b. Secondary injection testing.

  • This allows you to check the operation of the circuit breaker, relay connections and the relay assembly.
  • This testing method is conducted by injecting current to the secondary terminals of the device transformer. 

3.  Other Tests

  • Insulation resistance measurement

This test ensures that the insulation of the relay is within the acceptable operating limits. Ideally, the relay insulation should have a resistance of a few MΩ to TΩ.

  • Seal-in operation and target  testing

Most protective relays installed on electrical facilities are the seal-in and target combination. The test verifies that the contacts will seal-in to its close position with the minimum DC current.

  • Zero Check

This test is conducted on relays that has a time dial.  This test is done to determine the time dial reading when the moving contacts are closed by turning the time dial to zero position and the relay is fixed.

  • Testing Relay Pick-up

This will test the min and max frequency, voltage, current to close the relay.

  • Instantaneous Testing

There are some protective relays that operate instantaneously These types usually have a separate instantaneous component. This type of relay doesn't have any intentional delay. An instantaneous components at twice the pick-up must operate between 0.016 and 0.30 seconds.
