An apparatus for generating electrical discharge includes a component that generates an electrical discharge, a measurement circuit configured to measure a magnitude of the electrical discharge, and a controller configured to control the magnitudes of the electrical discharge. A method for controlling a reference partial discharge signal in an electric power system includes generating a partial discharge for built in self test, controlling an expected discharge magnitude of the partial discharge, and includes measuring an actual discharge magnitude of the partial discharge.

Systems and methods for operating a match network are disclosed. One match network comprises at least one first sensor to measure one or more first parameters and at least one second sensor to measure one or more second parameters. The match network also comprises means for assessing whether the match is operating as expected or operating outside of specifications using the one or more first-parameter measurements; the one or more second-parameter measurements; a setting of the match; or one or more expected parameter values.

Systems and methods for operating a match network are disclosed. A method includes obtaining at least one measurement-based-attribute at the first side of a match network and at least one measurement-based-attribute at a second side of the match network. A present reactance setting of the match network is obtained and a model of the match network is accessed that associates the at least one measurement-based-attribute at the first side of the match network with at least one expected-attribute at the second side of the match network based upon the present reactance setting of the match network. The at least one measurement-based-attribute at the second side of the match network is contrasted with the at least one expected-output-attribute to assess whether the match network is at least one of damaged or operating outside of specifications.

It is intended to provide an irradiation device that can achieve good starting performance even without encapsulating a starting performance promoting substance into the internal space of a luminous tube in a discharge lamp, and simultaneously, can distinguish whether the discharge lamp is a genuine product or not. An irradiation device (50) is composed of a discharge lamp (110) provided as a light source and an ultraviolet light source (200) irradiating ultraviolet light to the discharge lamp (110) to detect whether the discharge lamp (110) is a genuine product or not in activation of the discharge lamp (110).

A method and apparatus for nondestructive testing of a gas discharge tube (GDT) comprising: electrically connecting a first terminal of the GDT to a first port of a vector network analyzer (VNA); electrically connecting a second terminal of the GDT to a second port of the VNA; measuring S parameters with the VNA; determining GDT capacitance and insertion loss based on the measured S parameters; comparing the determined capacitance and insertion loss of the GDT with a threshold value to determine if the GDT is functional.

A method for monitoring degradation of a flashlamp including triggering the flashlamp to produce a light pulse, monitoring at least one parameter as a function of time to obtain a pulse waveform of the light pulse, comparing the pulse waveform to at least one reference pulse waveform to determine a difference therebetween, and flagging an end-of-lamp-life condition when the difference exceeds a predetermined threshold.
