1 Smart Primary Injection High Current Testing Product Line EPRI CBUD Users Group Meeting June

2 Why get Smart? Megger has had Primary Current Injection with: DDA Series CB Series MS Series ODEN Series So, why Smart Primary Injection. Use new technology to enhance the usability Lower the weight per watt output ratio How about 2,000 Amp in a 44 pound box? 2

3 Smart Primary Injection Target Applications Commissioning Testing Maintenance Testing Low Voltage Circuit Breaker Testing Pickup Testing Time Curve Testing Instantaneous Trip Testing High Current Primary Injection Switchgear Testing Heat Run Test CT Test Ground Grid Testing Test and diagnose corroded ground grids Recloser Testing Oil & Vacuum Minimum Pickup Test Trip and Reclose Timing Test Single Shot to Lockout Test Sectionalizer Test 3

4 Smart Primary Injection Goals Improve high current testing repeatability Reduce high current testing time Provide a means to compare manufacturer trip curves to actual test results Provide ability to database test results Simplify high current testing by automating process Provide report generation 4

5 Smart Primary Injection High Current Line Feature Smart Primary Injection SPI - Key Features SPI can be controlled by STVI or PC PowerDB is controlling software Benefit Permits users the option to control the system manually from a Smart Touch View Interface or use a PC to automatically control the unit. This simplifies training for both STVI users and PC users since the system uses the same application PowerDB benefits are immediately available, such as test report generation, database management, trending etc. Programmable output current SPI system compares test results against manufacture s time current curves Speeds testing by eliminating the manual variac. Every other high current system requires user to manually set output current. Eliminates the need for the user to manually compare trip times to a paper TCC curve 5

6 Smart Primary Injection High Current Line Smart Primary Injection SPI - Key Features Feature Automatically regulates output current to programmed value Multiple compact portable systems can be linked together to generate higher test current PC connects using Ethernet or USB cables Bluetooth enabled PC s eliminate communication wires Benefit Overcomes heating of the trip element which causes the current to drop during a thermal test Maintains a uniform current waveform even with changing load impedances Higher test currents can be obtained by adding multiple units (stacking). Synchronization between multiple boxes is obtained by a single Ethernet cable Wired communication & control is achieved by common high speed communication cables. Eliminates the users need for a communication cable. 6

7 Smart Touch View Interface Operation Simple intuitive interface specifically designed for: Primary injection testing Circuit breaker testing Ratio CT s Permits storage of test results in STVI Rugged and simple touch screen interface STVI Uses PowerDB as operating application Test results compared against manufacture s trip curves The STVI will ship with available breaker curves Additional breaker curves can be added by downloading from PowerDB 7

8 STVI Operation of SPI Results can be transferred with USB stick or Ethernet connection STVI connects to SPI using a common Ethernet patch cable Same STVI can be used on ANY SPI unit 8

9 SPI-835 SPI Smart Primary Injection Provides advanced testing features for existing CB-832 customers Able to test 225A circuit breakers 2000A maximum output Weight 20kg (44 lbs) Comply to Circuit Breaker Testing Standards NEMA AB-4 NMAC Breaker Maintenance Vol.3 NETA Testing Guidelines CE and IEC61010 compliance 9

10 1600A Breaker Test System 19,000A Max 2000A Breaker Test System 20,000A Max 3000A Breaker Test System 35,000A Max 6000A Breaker Test System 60,000A Max Future SPI Systems 10
