PJ Electronics

We are the only manufacturer that employsHigh Frequency Technology. High frequency technology is accomplished by use of a bi-directional switch whichno onein the industry has! (All competitor testers used in the market today use a uni-directional switch as the primary discharge device. This method of discharge is classified as an impulse and the te... ster in which this switch is employed is called an Impulse Tester, not a Surge Tester). PJ Electronics is the only manufacturer with an entire line of surge testers that exhibit a voltage rise time that meets the IEEE Standard 522-1992/2004, IEC 34-15 i.e., 0.1 micro-seconds. All of our Surge Testers resonate / pulse the load coils at 60 pulses per second. Typical Impulse Testers pulse their load coils around 5 pulses per second at a much slower rise time. PJ Electronics is the only manufacturer that can accurately generate voltage to any type of load and give 100% accuracy in the verification of our voltage and voltage rise time. Factory voltage calibration on all PJ Surge testers is traceable to NIST (National Institute Standards and Technology). Our customers can actually verify the output voltage, as displayed on the panel meter, for themselves at any time. This is accomplished by using an optional calibrated High Voltage Probe in conjunction with our Digital Oscilloscopes that we supply with every one of our testers. This test procedure can be seen by the illustration shown below: ALL PJ Surge Testers come equipped with a standard feature to test grounded or ungrounded Fully Assembled Motors without rotating the rotor. Whether your application for a Surge Tester relates to Manufacturing, Re-building, Quality Control, Preventive, Predictive Maintenance or Laboratory R&D, a PJ High Frequency Surge Tester will improve your product reliability by uncovering: flashRead More
