• Incorrect wiring method

22
Functions

• Anti-tamper for compact-meter

• Almost impossible to tamper when relay keep
  cut-on state.
• When tamper under relay cut-off , meter can judge
  customer tamper behaviors and transfer info into
  card when load credit to inform management
  department.

23
Functions

• Anti-tamper for split-meter

Prevent various tamper behaviors below the
metering unit
24

29
QUALITIES

• We took the best raw materials for example the
  PCB shell used for the meter are very strong, it
  is very difficult to damage if it fall down or
  hit by a very hard object.
• The LCD materials are all imported from Germany
  which can be used for more than 20yrs and it can
  with stand a very high temperature.

30
PRODUCTION TECHNIQUES

• We adopted advanced production technique jointly
  using the best parts and components from the top
  range producers in the world with zero pollution.
  Our factory has passed the ISO14000
  certification.
• We are using advance production equipment put
  together by computers automatically without
  interruption of any kind. This is the first
  modern special production line of china for meter
  production.
• We have a strict management of meter production
  according to advance quality management system.
  HENAN STAR is the first meter factory to get the
  ISO9001 in china. We have continue our meter
  production according to this quality standard for
  more than 10yrs

31
PRODUCTION TECHNIQUES

• We re-evaluate all the quality of Nigeria meter
  to meet the climatic condition, all meters
  delivered here presently are included, therefore
  we can confirm that no other PPM can be compare
  to our meters.
• Unistar is the first company in Nigeria to teach
  Nigeria how to make and install the prepayment.
  These expose us (HENAN STAR) to have experience.
  It is believe that we can offer all best
  technical and service support with the assistance
  of Nigerian engineers.

32
FEATURES OF PRODUCT

• We have all types of prepayment, we have single
  phase compact and split meter, three phase
  compact and split meters. We also have prepayment
  without wire i.e. remote control to control it we
  also have prepayment meter without wire
  controlling it (remote control) and also
  prepayment meters that uses key pads. Our meter
  also have the current rating of 100A and of
  course other smaller current rating like 40A, 60A
  etc
• We also adopted CPU card technique which nobody
  can open i.e. the datas are highly secret.
• This technique can be compared to the advance
  bank secret system. We also adopt the split
  technology to check tampering or by passing. We
  also incorporate the advance vending software
  system to be controlled on the meter and billing
  or vending on-line.

33

• FEATURES OF PRODUCT

• We have made use of the best software together
  with advance technique so as to ensure serious
  monitoring of the meter i.e. we can analyze the
  billing data and print the report to detect the
  customers that did not vend according to required
  amount.
• We also have a protection device in the meter
  incase the customer overload his or her supply,
  instead of fire the meter will trip off, the
  meter can be revive with the customer card after
  necessary correction on the load. However, we can
  design more electric meter according to Nigeria
  request

34
PRICE

• The price of our meters are very competitive
  considering there robust configuration, quality
  and efficiency. If you pay peanut, you get
  monkeys. Quality of PPM in an environment likely
  power outage cannot be over-emphasized.
• There is no other Split PPM manufacturer or
  vendor in the country known to us.
• Compact PPM already in use are obviously cheaper
  all over the world but prone to tampering.
• Our Split PMM come with the following value added
  functions
• It has high accuracy, stability and long life
  span of 15yrs

35

• The CPU card has data read back function
• International warrant against manufacturer defect
• After sales service in our local factory
• On-line vending facility
• Monitoring of each meter against tampering
• Difficult to by-pass
• Assurance of high recovery and higher revenue
  collection
• It has a high capacity for surge resistance
• It has protection against over load and theft.

36

• It has a tri colour LED to indicate the available
  credit level on the meter
• It can display cumulative energy consumption and
  operation recorded in turn
• It can identify on the LCD automatically the
  nature of fault on the meter. If at all it has a
  fault
• The meter case material is flame resistant,
  rainproof and is protected from dust and solar
  radiation
• It has radiator for solving internal heat
• The insulation test is 2Kv AC/min

37
Security

• One card, for one meter, and vice versa
• ESAM Module
• IC card with CPU
• 3DES encryption arithmetic
• 7 kinds of cryptographic key

38
Summary

• Digital design
• Metering, Data transmission, Display
• Comply with international Standards
• ISO14000,ISO9001
• Prepayment function
• Anti-tamper
• The meter has perfect anti-tamper functions
  because customers cannot access to the metering
  unit.
• Short-circuit, phase and neutral interchanged
• High security
• Smart Card, 3 DES, Seven Keys, ESAM Module
• Personalized design
• Installation, convenience, maintainability
• High rate of performance/cost

39
Summary

• We believe
• our meters can
• solve
• the fee collection
• and prohibit the behaviors of tamper

Increase the PHCN benefits largely
