Portable Meters
Three types of meters can be used for generator testing. They are elaborated as follows:Multimeter
It is a commonly used tool that provides insights into the device’s electrical properties, such as current, voltage, and resistance. It helps to diagnose the open, ground or short circuits that can hinder the functionality. They can be in-built or externally used. Further, the older versions come with a needle movement scale type device, while newer versions and digital ones do. Using the multimeter, however, requires knowledge for testing. To understand this, you must know how to test a generator with a multimeter, as current tests require the passage of wire through the diagnostic generator tools. Similarly, checking resistance also requires disconnection of conductors and coils, while voltage testing is possible without circuit isolation. Mutlietes can also be coupled with accessories and adaptors to enhance functionality. It includes an inductive pick-up/external trigger, integrated temperature probe, and pressure vacuum module.Megohmmeter
It is the insulation resistance tester, and the testing process is referred to as megger testing. The device circulates high-voltage low amperage through coil or wire and measures the resistance. The value over one mega ohm is fine; otherwise, there lies the need for the replacement of damaged or degraded stator winding insulation. New alternators need to be placed on the defective part.Clamp-on Ammeter
These caliper ammeters or clamp meters are of two types: AC and DC clamp ammeters. The functionality of both differs considerably. The clamp meter uses soft iron jaws that surround the conductor to provide contactless testing. The AC clamp ammeter uses variation in the magnetic field that arises due to that change in load, while the DC uses the hall sensor effect to provide the results. The clamp-on ammeter also measures capacitance, voltage, continuity, resistance and other properties. It is also available in digital mode.Advanced Diagnostic Tools
With the presence of a complex Programmable Logic Control (PLC) configuration and other critical, delicate and hard-to-reach parts, handheld meters aren’t sufficient for an in-depth generator diagnosis of the capabilities and functionalities. Hence, the advanced measures need to be taken, such as:Generator Health Monitoring System
These systems allow remote monitoring by integrating with the generators. Continuous inspection and monitoring of the equipment provide timely insights into potential or suddenly occurring problems. The features help avert large-scale damage or issues to both the generator and field workers.PULSAR Stator Core Testing Systems
Here, the stator core tests are done to check the condition of the rotors. The PULSAR offers an effective and safe approach to carry out the stator test. It is an alternative to the ELCID and HVRF testing methods that pose safety hazards and are longer in duration.
Robotic Inspections
It is the more advanced method of inspection that offers quick and accurate results. It helps gain actual insights as the probes and robots can be inserted into the area of concern. The robotic inspections are fruitful in identifying issues with core packets and corrosion on wings, stators and other parts.Revive Your Generator With Generator Testing
Regardless of the results you obtain from generator testing, you are reading the article at the right place. If your generator is working fine, it is recommended that the diagnosis be regularly repeated after a certain interval of time. However, if you encounter any issues, there is no need to bother. Your operations won’t halt for long. At CSDiesel Generators, we deal with everything from generator parts and accessories to new generators. Communicate your requirements to us and gain swift delivery to ensure seamless operations.
